I am just curious about what kinds of features make an appropriate venue for an earth cache. So many of the ones that I have seen have to do with rocks or water. What about trees in an amazing forest? An area that I am considering right now is an educational facility that teaches about the undeveloped prairie (plants, animals, etc.) since so much of our country has been developed and changed. Also, I have seen a bunch of earth caches around here that have to do with Lime Kilns. I just found a wood kiln especially used for the clay on the prairie. Would this work? I just hate to go through all of the work of research, finding coordinates, getting permission, etc. if it won't be approved. I am fairly new at this but I really want to get my platinum level!
Unfortunately, I have found it hard to search through all the listings for other examples of earth caches. Maybe there is a better way to do this? Your advice on this matter would be appreciated, thanks.
