As someone pointed out to me, I can hardly advertise a show in Arkansas without also advertising the upcoming show in St. Louis. So here it is: it’s the weekend before the Arkansas show, easily accessible from Kansas City, and I am sure it will be fun.
A fun show opportunity next month. Mountain Home is in the north-central part of Arkansas and is only 4 and a half hours away, same as a trip to St. Louis. If you like quartz, Arkansas is famous for it and I’m sure you will see lots of it. I also hear the show will have plenty of air conditioning!
The Association Picnic will be Sunday August 27 at Antioch Park. 6501 Antioch Rd, Merriam, KS 66202. Please bring a side dish or dessert and cash so you can buy something at the auction. Proceeds go to the Scholarship Fund.
Next weekend (June 10, 2017) we are going on a trip to the Missouri Mines Rock Swap in Park Hills, Missouri. We will look for drusy quartz and possibly Missouri banded agates. The swap itself goes from June 9-11 if you want to stay longer and is located at the Missouri Mines Historic Site near St. Joe State Park, 4000 MO-32, Park Hills, Missouri 63601. FREE admission to the show!
Directions: From Missouri 32, get off at Federal Mill Rd and look for the Missouri Mines Historic Site. Google Maps
Stalactites and stalagmites form in caves when water that contains dissolved minerals (such as calcium carbonate) drips from the ceiling. Scientists can analyze the 18O/16O ratios (isotopes of oxygen) in the stalactites and see how the temperature changed as they were formed. A team led by Andy Baker, Gurinder Nagra, and Pauline C. Treble of the University of New South Wales, Australia discovered that Yonderup Cave had a lot more 18O than they expected. Since having more 18O is associated with higher temperatures at the time of formation, it could have been interpreded as one of the largest climate changes in the last 2 million years.
But, there was a wildfire in 2005 and a large tree died right on top of the cave. Baker’s team believes that this is what actually caused the increased 18O concentration. This is important for anybody else trying to use these oxygen isotopes to determine ancient temperatures, because if they get a very warm result it might have been caused by a forest fire instead.
It’s a little more complicated than that. Read the whole article here: http://cen.acs.org/articles/94/i30/Cave-dripwater-contain-fire-evidence.html and check Baker’s website for more interesting stuff about how he researches caves to learn about past climates.
In this economy, we all could use some career advice. Here is an interview with a former curator of the Denver Museum of Nature and Science, explaining how he got the job and what it entails. (more…)
The Spring 2017 Gem and Mineral Show was very successful. The parking lot was filled to capacity and we made over $3000 for the scholarship fund. I think it helped that it was so cold on Saturday, because people wanted to do something indoors. Here are some of the highlights.
We hope you are having fun at the show. Don’t forget to set your clocks forward 1 hour for Daylight Savings Time.
