bouldered

In one video, a small tube of a “melt cast” explosive punches a deep socket into a heavy metal bar, detonating so loudly the sound rockets from one bouldered slope to another.

The walls mimic a cave and the water echoes against the bouldered ceiling.

Sunday specifically bouldered into the end zone for a one-yard touchdown with the third team on Saturday, and also exploded around the right edge for a 19-yard gain.

At exasperatingly frequent intervals, the path was broken by steep, thickly bouldered streams, frozen solid and ribbed with blue ice, which could only be negotiated in a crablike crouch.

I’m left 10ft back, hurrying to follow him up and down the bouldered arroyos.
