One of America’s longest lava tubes intrigues with its geologic features

written by Joni Kabana

Who isn’t thrilled by the idea of what lies beyond the opening of a deep, dark cave? The mystery, the giddiness about potential claustrophobia, the notion that buried treasures might be found–all fodder for the imagination.

If this sounds interesting, then hightail it over to Ape Cave, North America’s third-longest lava tube, which features moderate to difficult terrain and a smaller, family-friendly path. Be prepared for slippery conditions along the 2.5-mile hike (wear appropriate shoes) and pitch-dark surroundings. Are you still game? If so, bring a coat even if it is summer because the temperatures are cold (hovering around 42 degrees) in this neck of the woods, as well as two lanterns per person as cellphone flashlights are not bright enough. Ape Headquarters, a small information station, rents lanterns as well.

Ape Cave, located near Cougar, was formed about 2,000 years ago when an 8-mile-long lava flow cut its way through the earth. Some molton substance continued to move and eventually cooled, forming a crust on the earth, and a cave. Unique formations can be seen inside the cave, with some of them acquiring nicknames such as “the Meatball” and “Railroad Tracks.” Its name came from an outdoor group (called the Mount St. Helens Apes) who frequented this area in the 1950s.

Ape Cave is open from mid-May through the end of October, and reservations are required. Consider going midweek to avoid weekend crowds and parking. Because, after all, don’t you secretly want to get lost in a cave and come out the other side in a technicolor cartoon just once in your life? Do come prepared for the uncanny, though–sightings of Sasquatch indicate you just might come across him while taking your leisurely stroll through that dark tunnel.
