In June I drove up to Mount St. Helens from Portland, Oregon mainly to visit the Ape Cave. The cave is located in the Gifford Pinchot National Forest and with its 4023 m length, it is the longest continuous lava tube in the continental United States. The Ape Cave is sustains a population of the endangered Mt. St. Helens grylloblattid or ice crawler, a member of the rarest insect order on the planet. Location: Ape Cave. Date: 22.06.2017.
