Luna and I found a tiny cave on our hike yesterday. Well... "cave" is probably an exaggeration. Grotto? Outcropping? Alcove? Dunno but it was pretty cool.
Luna sniffed it and does not appear any animals spending much time in it. Hard to tell from the pics but roughly 10 feet wide, 5 feet tall, and 6-8 feet deep. Easily fit a half dozen folks for a picnic or break from the sun/rain.
No beer cans or junk food wrappers so the local teenagers have not found it yet.
