Day 138: Deep and dark

Day 138:

This chasm that my tunnel came out at on my way east to the big mountain (bigger mountain?) is deep, and at the bottom (or at least as far as I can see) is a load of valuable granite.

Digging down a vertical shaft isn’t nearly as easy as digging across a vein, especially when I lack rocket boots or inertia dampeners.

I’m spending a lot of time making bracing and rope structures for the walls just to try to prevent myself from slipping to my death.

I don’t feel like I’m making much progress, is what I’m saying.

roughly the same line sketch as day 117 except now the ravine has stairs and platforms sketched in between the walls, and an arrow pointing down to let the reader know there's good stuff somewhere down there.
I add the stairs after I get the floor in, for obvious reasons.
