Ranger Sarah has reached the end of the self-guided section of the Lava Tube. The lava tube continues for quiet a while after that point, and more might be open in the future.

Ranger Sarah hikes deeper into the Lava tube. The bones of many different bears, including the huge short-faced bear, along with camels, buffalo, and little horses, have been found within its dirt floor.
