  2. Blister Cave: 2023 guidebook page 7.
  3. Breakdown Mountain Cave: The cave is named for the prominent breakdown mountains in the cave. The small entrance sink, 8 foot deep, leads through a low opening (4 feet high) to a more spacious cave with 15-25 foot ceilings. Also known as “Lower Falls Creek System” with about 200 feet of passage at 2570 elevation.
  4. Datus Perrys Cave,  part of the Falls Creek Lava Tube System, was reported to Oregon Grotto in early 1968 by Datus Perry, a long-time resident and inveterate cave digger of Carson Washington. Best known for its lava stalactites and stalagmites, parts of the cave were photographed by Charlie and Jo Larson on May 19, 1968. Two photos depicting a two-foot lava stalagmite “before and after being broken,” included in the 1980 Oregon Grotto Slide Show, were actually photos of the stalagmite as found (broken) and of it reassembled. In 1975, Oregon Grotto members surveyed 800 feet of the cave before the survey was abandoned because the cave was too cold for “shirt sleeves.” Cave is more likely around 1850 feet in length, as several leads have pushed it significantly over the years.  Speleograph trip report by Libby Nieland Vol. 11 page 129. And Underground Express by bill Holmes 18 (3): 27. –several 1968 trips planned (Speleograph 4(7):1)
  5.  Datus Perry’s Dug Cave: This guy was digging through breakdown in a big sink in the northmost Falls Creek Cave area. Two digs attempted to drop into the main passage, but both were never finished. The right side dig travels about 120 feet through a mine-like dig with timbers holding up the ceiling and a “Falls Creek Lava Tube” post near the end.
  6. Double Eagle Cave: (584 feet) 2023 guidebook page 7.
  7. Falls Creek Cave: 633-204. About 7200 total feet with about 4300 feet in the main part passage. There are three parts of the cave separated by collapse sinks. The main passage bears an 800 foot long side passage, and several intertwinning passages throughout. The cave ends at a large lava chamber which has three levels. (AKA: Panther Creek, Lava Caves). See Caves of Washington for full write up.
  8. Falls Creek Falls Cave: The lowest of the Falls Creek Cave system, it is about 800 feet long, and contains some original passage, as well as crawl, and a side passage. The sink it is located in an area that makes it hard to find, and has an upslope section of un-opened cave must exist, but hasn’t been breached at this moment.: See Speleograph Jan. 1986 page 7. Found By Detus Perry.

  17. Risky Business Cave: Next cave upslope from Three sinks Adjunct Cave, this brittle section of tube is filled with loose rock, and breakdown. Strong wind near the end suggests the cave continues through the breakdown, but the unstable nature of the rock makes it very dangerous to dig in. Cave was eventually pushed in June of 2016 and added 2250 feet of new passage. The new discovery filled in the large gap of missing cave, and most of the passage is nice walking with ceiling height ranging from 20 to 40 feet high. Spleograph 451 story and new map.

  21. Three Sinks Cave : At 2,800 feet map length, Three Sinks Cave is the second longest know segment of the Falls Creek Lava Tube System. Cavers learned of the cave from an Oct., 1967, letter from Clay Beal, then a U.S.F.S. Disrtict Ranger, to Bill Halliday which was forwarded to Oregon Grotto. First known cavers to visit the cave were Charlie and Jo Larson who found it to be a world class example of stream flow, sedimentation and subsequent erosion of pyroclastics in a lava tube.  Oregon Grotto held a Forest Service special use permit for several years; currently the cave enjoys special protection by the Forest Service.       Trip report Speleograph 359 page 8. Three Sinks Adjunct Cave: Upslope about 200 feet from Three Sinks Cave, this 200 foot long section of tube is fairly large in size, and contains a small section of sand castles. A piece of ceiling breakdown has made a nice bridge to cross the area.     Trip report Speleograph Ja. 1986 page 8.
