My husband and I tried geocaching this weekend! Armed with a GPS and an iPhone with the geocaching app, we searched for three geocaches (out of hundreds to choose from) in our area. We started with an easy one at Lynx Lake, where we had lunch- I think it took us about 20 minutes to find. Then we went out to Willow Lake and quickly found another (a tiny one this time), although it took us about 20 minutes also, most of which was spent tromping through weeds and climbing an embankment to get to the location.
Our confidence high, we tried to find a third one hidden on or around the granite boulders closer to the lake itself. It was an educational geocache in that there was a quiz as part of it, based on the information the cache hider provided about the Liesegang bands or rings found atop the granite rocks at the location. These bands are concentric circles or rounded squares formed by a chemical process involving erosion and minerals and other things beyond my comprehension. And they are pretty amazing to look at! I can attest to how cool they are, because I spent a good hour and a half looking at them as we searched for the cache. I kind of gave up about halfway through, because the iPhone battery gave out (why didn’t we bring the new portable charger I just gave my husband for his birthday?). My husband had become pretty obsessed, though and was charging around determined to not be beaten. But beaten we were- at least for this weekend- but we’ll be back!

You can’t fool me , you and Lonnie were out there with your permanent markers making those designs and you did a great job !
Amazing-how fortunate you are. T.
How cool is that! I’ll have to go check it out in person!
I’ve never seen anything like these rocks. Very fascinating. I love the second and third shots because of the unusual subject but I’m drawn to the first because of the lonely little tree. Very nice
