I went on a hike with my roommate!

 so, yesterday, 3/31 around noon, my roommate and I mostly followed the mariposa trail in the Irish Hills trails (up behind Costco). 

this rock I found in a dry creek bed. the patch of greenish blue on top caught my eye while we were walking, though I'm not sure exactly what type of mineral or rock it is that makes it that color.

here's me with the rock, its a good third of the size of my head if I were to estimate

I really like rocks, I collect rocks that catch my eye, and a bit farther down the path, I found this neat little piece of what I think could be serpentine. my grandma knows a lot about rocks, and I remember her pointing out serpentine while out on trails here in SLO.
