I found a cache a few weeks ago with little snow. It wasn't frozen in - and was a very unusual container.......but the cover which was threaded was frozen on tight! Because of the material and design, I did try to bang the cover loose = no luck! I think if some vaseline had been placed on the threads it wouldn't have frozen shut. So being unable to sign the log, I didn't take the find.
My daughter suggested had I taken my bag on the hike, I could have put a sticker on the outside of the container or signed it with a Sharpie marker. She always has great ideas. Of course a sharpie sign on a ice cube would melt - and the sticker would become geojunk! LOL
Pelican cases - they rock. Last year, after Marden's bought out a sporting goods store, I found some there. They were small - about the size for a wallet, cell phone or cache - $1.49/each. I really didn't realize what a buy they were so only bought a few. I should have bought the whole display! LOL Anyway - if anyone is close to Marden's that is something they have been known to carry.
