I actually did want to do an Earth cache because the place is steeped in history and I thought it would be nice for cachers to explore that, however an Earth Cache needs to be specifically about geology not about history. The basis of what I want to do is to share the history of the area with finders, so it looks like I might have to do a multi-cache (of which I am not a fan and wanted to stay away from). Thanks for the tips about the pictures too. I might have found over 1000 now, but I’ve never actually hidden one (I have adopted 3), so am definitely a newbie in this area. I also know how annoying it is when co-ordinates don’t match up with the actual location, so I’m pretty nervous about the whole thing!
