President's Corner

Evan D. Elliott

 

Thanks are warmly extended by all to Mike Trafton, for his very interesting presentation of his video work-in-progress about the Denver Gem and Mineral Show and the Sweet Home Mine.

 

For March we will have our "Silent Auction". I encourage all attendees to bring material (gems, jewelry, mineral specimens, etc.) to sell so we will be sure to have a plethora of items to peruse at the auction tables. We need material for the kids' table too.

March Meeting (Mar. 13)

Alex Cook

 

The time has come, folks, for our annual silent auction, so gather ye round for another exciting time. The date is March 13th, the time 7:00 p.m. Bring your items for sale to the West Side Senior center prior to 7 o'clock. In this bulletin you will find copies of the slips that you need to fill out, or you can obtain same when you sign in. Each seller will be assigned a number that must be entered on the sale slip. The club keeps 25% of the final bid, or more if the seller so indicates on the slip. A minimum bid price may be entered on the slip if the seller desires. If no percentage is entered, it will be assumed that the item is being donated to the club. Each buyer will also be assigned a number that will be entered beside the buyer's bid. Minimum bids are 25 cents over the previous price or whatever the seller designates. There will also be a kids table where it is assumed that the material is donated and at which there will be no minimum bids or minimum increments.

 

The auction will start as soon after 7:00 as we are ready. The tables will be numbered, and after about an hour of bidding one of the tables will be closed and the others later at various intervals. The bidding should be over by 9 p.m. at which time the money for the successful bids will be collected. Sellers will receive their money through the mail at a later date.

 

All club members are requested to bring something in the way of snacks or nibble foods. The club will provide drinks, plates, cups and serving utensils. For questions or information contact Evan Elliott or Alex Cook.

 

Bid sheets are now available.

Change to the policy by the City of Boulder on the "FIRST ADMISSION TIME" for our FMC monthly meetings at the West Boulder Senior Center facility, effective March 1st

Gerry Naugle, FMC Treasurer  (and liaison with the City)

 

As part of the new "security planning measures for city facilities" including the Boulder Senior centers that have been recently adopted by the city council in response to national directives along these lines...our room rent time for our monthly meetings starts at 7 p.m. on the Thursday evenings of our monthly meetings. The front-desk lady has been instructed by her supervisors to allow us a 15-minute grace period, only, [new policy] prior to 7 p.m. to be admitted to the building and 15 minutes after 10 p.m. to exit. No Exceptions.  

 

So, please arrive no earlier than 6:45 p.m. on any meeting night. Also, please don't debate or argue the merits of this new policy with her, as she is just following the general direction and instructions of the Boulder City Council, in their response to national issues. If you have any problem with the new policy, please bring it up with a city council representative or just show up at one of their regular city council meetings.

 

I explained that some rock hounds are by their very nature "early birds" but to no avail. The reasoning behind this new policy is that: "they don't want people wandering around the buildings before or after any scheduled meetings" [the facilities security aspect]. FYI: this applies to all meetings of any non-profit groups at any of the major facilities within Boulder, except the recreation centers, which just have fixed building opening and closing times for the public.

 

If it applies, thank you for adjusting your arrival time to be on or after 6:45 p.m. for our March meeting and subsequent, in order to accommodate their new policy.

From the Field

Paul Boni

 

I received an email in February from a slightly frustrated member of our little club. The message concerns a common theme that crops up from time to time. In fact, her message is so beautifully articulated that I thought it worth sharing, along with my response.

 

 "I am a bit disappointed in my experience in the club and attribute that mostly to my own decisions, but think perhaps other newbies would have a similar feeling in that I'd hoped to really learn how to go out into the field and find treasures and to do it. My experience so far is that most people on the trips are understandably eager to find their own treasures. On occasion, I've attached myself to members such as you who seem willing to talk about what we are seeing and how to look, but perhaps it would be worthwhile to set up some trips especially for that purpose. What are the signs? What are the basic tools? Where should one go on one's own? What are the necessary precautions/arrangements? For example when I heard Evan talk about going to Utah, I had no idea how he set that up or, if I wanted to do the same, how to go about it. It's probably like anything else--once one has the experience, one forgets how little others know and how intimidating it can be. I consider myself an adventurous person, but I hate wasting my time due to lack of knowledge. I have read some books, but don't find that the best way for me to learn (although it may work well for others). I've been frustrated by my lack of knowledge, realizing I probably walk by signs that would indicate the presence of delightful specimens to a more experienced collector. It takes a while before one knows the right questions to ask. I've appreciated getting to know people in the club and would like to thank those who are so helpful and friendly."

 

Your insights regarding disappointment with the mineral club are worth paying attention to and I think, not uncommon. I felt very much outside of things when I first joined myself. Although I had some prior experience collecting (my thanks to two terrific friends) and a geology degree, it took a couple of years before I felt "integrated" in the club. Much of the problem in my case is that I am something of a loner.

 

Conversely, we, the active "core" of the club, wonder why there is not more participation by our members. We really do try to offer interesting opportunities and activities. But when few, if any, take advantage and participate we can't help but question the interest level. It is frustrating to put something together and then have minimal participation. My answer and advice is to become more involved. There is more going on in the club than monthly meetings.

 

On Wednesday evenings (when there is not a club meeting that week) a few of us can be found at Charlotte Morrison's house. I have been teaching lapidary when there is interest, Terry has the slab saw running full tilt, and we have been stuffing and labeling samples for the grab bags. It is an informal but regular gathering and all club members are welcome to participate. It's a great way to get to know other members better, pick their brains, and get something done. The sale of grab bags at mineral shows is the vehicle that the club uses to support our scholarship grants. It is edifying work. Andrea Elliot could use more help with the club's mineral show that will be coming up in November. This kind of event doesn't happen without a great deal of preparation.

 

Your questions regarding "how to find ones own treasures" are valid and difficult to answer in simple terms. The game changes with each new location and geologic terrain. There are no all-inclusive answers that cover all.  Attention to detail and a little research before hand are a big help. But there is an element of subjective experience and luck involved. My best advice is to keep at it. Go with friends, the club, or by yourself, it all helps. There are several good books in print that describe collecting locations for every state in the union. Mineral hunting is one of those things that grows on you and in you. With time and experience your prowess will grow.

 

There are a lot of ideas and a few budding plans in the making. When the weather is more predictable, regular field trips will begin again. Even now there are rugged individuals who have been collecting throughout the winter. One of these is an undaunted and enthusiastic "newbie." Their plans and activities are too spontaneous ("looks good today... I'm gone!") to include a group. I attempted to leave things open ended this winter, for people to call me, to see if there are any spontaneous trips happening as the weekend approaches. Throughout the entire winter so far, I have received only one such call. My take is that there is little interest among the general membership. Lew Yoder is leading a couple trips (February and March) to local museums of common interest (Yea Lew!). Weather is not a factor with such plans and the museums he has chosen are very good.

 

I am researching some ideas and will report as workable plans take shape.  It is my intention that May will see us in dirty holes scratching away for buried treasure. I wish we could have a field trip every weekend!  I plan to lead a few (3 or 4) trips this season, but cannot give every weekend to the club. I am also approaching other experienced rock hounds to lead trips also. I certainly don't know all the sites, but am happy to share what I do know. By the way, this is the time to put in your requests for specific field trips and I'll see what I can put together.

 

In summary, we are a club, brought together by a common interest in minerals, fossils, lapidary, associated crafts, and geology. My experience has been that the more involved one becomes, the more one will benefit from the effort, both in terms of increased knowledge and social connection. Greater participation by all our members will enhance every experience that we share together, for the newbies and ol' hounds alike.

What To Do If You See A Fireball

From The Gates Rockhound Bulletin, June-July-August, 2002

 

A "fireball" meteor is a rare and significant event, and if you are a witness to one, concentrate on the whole phenomena for as long as it takes. Some things will occur simultaneously (over a short amount of time: light, sound, and changes in direction). Try to take it all in, and use the following ten steps to help you recall the fireball so it can be located by researchers looking for meteorites on the ground.

 

1. Keep your eye on the ball of light and associated phenomena, and count slowly (1, 2, 3, etc.)  until it disappears.

2. Note time of day.

3. Listen carefully for any sounds at the same time as the light and up to two or three minutes later.

4. Notice landmarks, buildings, poles, fences, trees, etc., below where you first saw the fireball and where you last saw the fireball.

5. Notice the height above the horizon where you first see it and last see it. (You can use landmarks for this too.)

6. Pay attention to the end: Did it fade out, blink out, fragment, explode - and - what about pieces falling off? Try to keep a mental/visual image of the event (was it shadowed, color, light intensity, flickering and end).

7. Watch for a smoke or dust trail after the fireball: Was there a smoke trail after falling pieces ... after the fireball?

8. If you are under the fireball listen for falling objects, even small marble or hail like pieces, or where larger pieces may have hit and could be buried in the ground.

 

After the event ends:

9. Memorize your exact location so you can return with a field researcher. (Write down notes and a sketch of what you saw with landmarks noted.)

10. If you have a compass, take a bearing and plot your location on a map.  If you have a GPS receiver, take a latitude and longitude reading.  Directions of first and last sightings and the first and last angles above the horizon are very important. For field researchers, this is the best way to locate the flight path and end position of the fireball; therefore any compass bearings you take become very important information.

 

If you think it is a significant event, you may want to report it on the Internet.This will allow researchers to use your position and observations to triangulate and locate the longitude and latitude of where the fireball breaks up in the sky and ultimately, to describe a potential impact area on the ground where meteorites might be found.

 

To report a "Fireball" sighting: Write down as much information as possible, based on the above questions, and mail to: Denver Museum of Nature & Science, Department of Geology, 2001 Colorado Blvd Denver CO 80205

Or call and leave your name and telephone number: (303) 370-6445 or (303) 370-6473.

Minutes of the Board Meeting, February 10, 2003

Emily Epstein, Secretary

 

Present: Paul Boni, Alex Cook, Evan Elliott, Emily Epstein, Ray Horton, Charlotte Morrison, Gerry Naugle, Paul Ralston, Melinda Thompson, Brad Wilkomm, Lew Yoder

 

The meeting came to order at 7:30.

 

Since Brian Welty is no longer a member of the club, we need a replacement Board member. Evan will seek volunteers at the club meeting on Thursday.

 

Gerry Naugle gave the treasurer's report.

 

Gerry reported on show arrangements. He and John Hurst have contacted 27 dealers, and probably will be contacting more. We have a verbal contract for the building, and the paper contract will be signed in March or April. Gerry and John are working to get things formalized as soon as possible. We have 68 tables available from the Elks, and can get more from other sources. We will borrow skirting for the tables from the Denver show. The club will have to arrange for members to assist with teardown so we can collect the skirting. The Elks have a meeting on Thursday night, during which outsiders are not allowed in the building. After some discussion, it was decided to move the opening of the show to noon on Friday, beginning setup at 8 a.m. Security concerns were discussed. Discussion of whether or not to charge admission to the show was tabled until the March Board meeting.

 

Charlotte Morrison has a number of passes to the Intergem Show February 28-March 1. They will be available at the meeting on Thursday.

 

Alex Cook announced that the Denver Council meetings conflict with other commitments. We need to replace him as Council Representative. Gerry Naugle volunteered to attend the March meeting. Alex said he could probably attend the June meeting.

 

The Board discussed the Silent Auction. Alex has some material that was donated to the club, which will be auctioned. Someone will have to go to the shed to get some more material. Auction slips for sellers will be included in the next issue of Facets.

 

Alex announced that Mike Trafton would be the speaker at this month's program, and said anyone who cared to come was welcome to join them for dinner before the meeting.

 

Charlotte announced that people are still working on grab bags on Wednesday nights. We need more minerals, especially from field trips, and urged everyone to bring flats of material for grab bags to her house.

 

Charlotte urged the board to resume having a showcase at club meetings, to encourage people to put together showcases of their own material for the Club Show. Melinda Thompson agreed that this is a good idea. Some newer members are not familiar with what a show is and what's involved in putting a case together.

 

Evan Elliott announced that John Rose has contacted him. He wants to sell a flat lap.

 

Coming events were discussed. The Fort Collins show will be March 21-23. It might be possible to arrange a carpool.

 

Possible venues for the club picnic in August were discussed. The most promising and affordable that Gerry had found was Boulder Parks and Recreation. The weekends of August 9 and 16 are both available. After checking the dates of the Contintail, it was decided that the picnic would be on August 16, in a park shelter. We have our choice of 11-3 and 4-8 time slots. The Board was evenly divided. Gerry will ask the membership at the club meeting which time slot is preferred.

 

The meeting adjourned at 9 p.m.
