Nevertheless, today it's hard to stroll for a distance of even 4 miles within any one lava tube. Large parts of the roofs of most lava tubes have fallen in, hiding the ground underneath large piles of angular broken rock, often stacked so tightly that entry to each upstream and downstream portions of the tube is closed. In some places, nevertheless, collapse of the tube's roof has supplied a large entrance into the lava tube through which one can walk with ease.
Lava Beds National Monument has the largest focus of lava tubes in North America. One has electrical lighting; the others are illuminated by ceiling collapse portals or require flashlights, available on mortgage. Volcanic eruptions on the Medicine Lake shield volcano have created a rugged landscape punctuated by these many landforms of volcanism.
It is released in a fountain of lava, blown into the air from a central vent. The lava cools as it falls, forming cinders that pile up across the vent.

One notable ground crack, the Big Crack, extends along the northeastern boundary of the monument. The lava is thrown out of the vent and builds, layer by layer, a chimney surrounding the vent. Blog Post Underground Adventures Apr 2018
