My youngest sister and her family live in Montana. They know of several places where trilobites are very plentiful and have collected some. Hubby and I haven't been to Montana yet, but I told my sister I'd really like to find a trilobite. She's happy to take me, but says that the locations where you get the best trilobites are only accessible in the summertime (the areas are snowed in for winter). The only TINY problem with THAT is summertime is when they routinely get massive WILDFIRES all through that area. Dang. I don't want to go fossil hunting badly enough to outrun wildfires!!!!!!!
