The "best preserved specimens" of the Florissantia quilchenensis (stonerose) can be found at the Stonerose Interpretive Center. In the store you can see all kinds of amazing fossils that have been found at the location, books, postcards, souvenirs, etc.
But that's not why you go to Stonerose, you go there to dig! The dig site is only a short walk up the hill from the interpretive center, so after checking in with the workers at the office, they let you free to explore & dig on your own!
For a fee (see below) you can spend the whole day chiseling the shale (volcanic ash turned to sediment). You are almost guaranteed to find some kind of fossil while you are digging whether it is lake bottom material, a ginko leaf, or the prized stonerose.
Sometimes you don't have to look far to find a fossil, you might just turn over a discarded piece of shale and find a stonerose like we did! We also found a ginko leaf, lake bottom material, and lots more. It is impressive if only for the fact that it's 45 million years old. When you first split a piece of shale it will be wet, so if you touch the fossil you will smear it. For that reason you have to let it air dry after splitting for a while before you can touch it.
This is a great place to engage the aspiring scientist both young and young at heart.
When you have completed digging and splitting and chosen the fossils you wish to take home (there is a limit of 5 I think), you take them back to the center and someone will assist you in identifying what you have found and help do some more delicate chiseling to reveal even more of your fossil than you thought was there!
The Details:
The charge is $8 per adult or $5 for kids 6-8. Kids under 6 are free. College students and senior citizens $5.
You can rent a hammer and chisel for $5, or bring your own (1/2 inch cold chisel is recommended). You can use screwdrivers or putty knives too if you really want to.
We actually purchased a yearly membership to the Burke Museum in Seattle (which gives you free admission to the Burke Museum, Port Townsend Marine Science Center, and the Stonerose Interpretive Center! The cost of the membership paid for itself with our visits to all these places.
They are clear that they reserve the right to keep any specimens that one might find that could be useful to the center or other scientists. If you are so lucky to find something like this, they may keep it, and should later contact you about it so they can let you know what's been done with it, or arrange to send it to you when they are through with it. I wasn't so lucky to find anything THAT cool, but one can only hope I guess. I wouldn't let that possibility stop you from doing this as a day adventure because it sure is fun. read more
