Obsidian

A hard, dark, glasslike volcanic rock formed by the rapid solidification of lava 

without crystallization.

I'm out East.  Spending time with my folks.

But I saw this arrowhead on my dresser and it reminded me of a ski tour I did a couple years ago.  

From the Birdhouse, over Daisy Pass, and down to Woodbine (via the Mighty Stillwater!)

I found this arrowhead doing trail work about eight years ago,

within a stones throw of where I saw these goats chillin.

(between Goose and Glacier Creeks)

I think there was even talk of putting a railroad through there.  About 120 years ago.
