Four Mile Run, from about a month ago, on a nice warm day while I was geocaching. I had climbed down to the water and upstream a ways in a vain search and stopped to admire the scenery.

I also spied this. I’m guessing metamorphic, which might be a gneiss guess, but I don’t know schist from shinola.

When I decided to leave I forgot Spengler’s advice and I crossed the stream. Turns out wet rocks are really slippery because of the slime on them (curse you, low coefficient of friction! Mu-uuuuuuuu!). I fell in (only up to mid-shin, and it was a mild day, so no big deal) but also banged my elbow, which took a week or so to un-stiffen.
