  Beaver Bay cave: Beaver Bay Cave is a lava tube segment that was abruptly truncated by mass wasting of a canyon headwall. Entry to the cave is complicated by talus resulting from ceiling collapse and hydraulic undermining of the tube floor. About 500 feet, map length, it is mostly low passages and rough crawlways.
   Found and named by Clyde Senger in March, 1977

 Becky's Cave: Name By Jim Nieland after forest service worker.120feet of tight crawl. Trip report Speleograph 362 page 4.

 Blood Cave: Denny Mt: Story Cascade Caver Sept. 2010 Vol. 49 #4 Page 10

  Blue Ribbon cave: 631-08A, B. About 500 feet of crawl.

  Breakdown Cave: Very large sink but short on passage. Closed winter for bats.

Breakdown Cave is the key to locating the Utterstrom's System. The massive entrance sink, being 110' by 50' by 25' deep is easy to spot and close to an old logging spur. The entrance, in the south end of the sink, is a small breakdown chamber. Look for ice in the west side of this room. The cave continues 75 feet to a breakdown choke with several deadend crawls and usually a little ice even in August. Breakdown is present throughout.

Discovered by Bill Reese and Cascade Grotto member Jan Utterstrom, first described by Bill Halliday following a June 1963 visit.

  Charcoal Springs: Vertical drop through tree mold into a nice cave under lava flow. 420 feet of passage.

 Christmas Canyon Cave: Complex erosional cave. 2637 feet of crawly passages. Water flows out cliff entrance during periods of heavy rain.

Stream-eroded cave in pyroclastics. Reported lengths vary. Early maps show less passage.
This is an erosional cave lying beneath the basalt cap rock at the head of Christmas Canyon.  During periods of heavy runoff a stream flows through the cave and emerges at the entrance as a waterfall spilling over a 12' embankment.  Storm runoff has been observed infiltrating the lava flow edge several hundred feet east of the entrance, near which water can be heard beneath the lava flow surface.  From the sound of running water in tree casts, and through cracks, it seems most likely that this is the recharge area for the cave.  No water has been observed in the cave except during intense rain storms, or rain on snow events.

Ole's cave: Ole’s Cave was found in 1895 by Ole Peterson, a hermit-type man who homesteaded near where the  Swift  Power Canal  is now located. Ole was a great story teller, and like all story tellers he exaggerated and added extra things to make his stories exciting. For this reason, it is uncertain whether Ole found the cave on his own or if Indians led him to it.

After finding the cave, Ole blazed a trail to the lower entrance and began giving tours, making Ole’s Cave Washington’s first tourist cave. Today, however, Ole’s Cave could be considered a 'wild cave' and is only visited by those people who know of the cave and can locate its unmarked entrances.

The first of many caves to be found in the area, Ole's Cave is still one of Mt. St. Helen's longest lava tubes at over 6,500 feet in length. Most of the cave is one continuous tube, but there are numerous small upper- and lower-levels to explore. Ole’s cave has much variety and is well suited for both novice and experienced cavers. Most of the cave is walking passage with original floor, but a couple of places require hands-and-knees crawling and there are significant sections of breakdown (broken rock) that must be climbed over. For the more adventurous, the upper- and lower-levels may be explored.

Cave formations in Ole’s Cave include lava stalactites and stalagmites, splash rings, flow marks, a pillar, and even a rock outcropping resembling the profile of George Washington’s face. In the entrance sinks (there are five entrances), different mosses and ferns may be observed.

History and pictures in Speleograph 381. 

 Pat's cave:

Perserverance: If you can get pass the long crawl you will come to a very nice complex cave with skylights and little formations. 1596 of passage. 

 Pillars of Hercules Cave: Many pillars in this cave. Cave is closed and gated. 2785 feet.

 Prince Albert Cave: One of the best railroad track formations at Mount Saint Helens. 2100 feet.

Prince Albert Cave was discovered but not entered on March 4, 1967, by Charlie and Jo Larson.  The Larsons returned to the cave with Oregon Grotto members Paul Grebstad, Reed Dow, and Wayne Larson on the following weekend. Handicapped by heavy snowfall, they were unable to thoroughly explore the cave, but did find a well preserved Prince Albert tobacco can on a ledge in  the down-slope section, after which the cave is named. 
    Unlike the typical lava tube it is complex up-slope as a braided tube then becomes more unitary down-slope. Considerably more complex than most other Cave Basalt Caves, this shallow cave's configuration can be assigned to pre-flow topography. Three entrances–a collapse sink and two skylights–provide an unusually extensive twilight zone beautifully adorned with over 25 species (#0914) of shade-tolerant plants. Special care is called for when visiting this cave. While the plants are not unusual–they can be found  nearby, as well as in similar microclimates all over the Cave Basalt–this luxuriant assemblage is easily trampled and disturbed . Equally susceptible to damage are a great many brittle lava formations, and the first silica drapery reported in the Northwest.
    An interesting primitive, campodeid insect (Haplocampa sp.) has been collected in Prince Albert, as well as in several other widely-separated caves in the Cave Basalt. These unusually large (1/4-inch-long), poorly known troglobitic species inhabit cavities in the Cave Basalt and underlying strata (their primary home), and  is strictly a casual visitor in proper caves.
    The only significant recent rockfall in a Cave Basalt was noted in Prince Albert when, sometime prior to 1974 but after the cave was mapped, about a ton of rock fell from the ceiling in the entrance area, narrowly missing the "Bathtub," and opening another small skylight. Prince Albert and Dollar and a Dime caves were featured field trips during the 1972 NSS Convention in White Salmon.

  Quarter cave:300 feet. Trip report Speleograph 359 Page 4 unnamed cave in report. Small sink with metal plate on tree. Jim N. found a quarter in the cave and so gave it that name.

  Red Pencil cave:

  Red Rock: Just a little hole with red lava near Lake cave.

  Red Stain cave. Powerline area. not found.

 Rock Pile cave. By Large rock pile. 

 Powerline Cave: Closed for bats.

 Railroad Tracks: Parallel lava levees give this cave its name. Nearly free of breakdown, it has a slot-like ceiling resulting from incomplete closure of the trench roof. By late August, 1980, a small mudflow tongue had entered the entrance area, otherwise the cave was unaffected by the 1980 eruption of Mount St. Helens.
   Forest Service records note that "this cave has attracted attention of cave biologists.

  Salal cave: A neat cave with lots of tree mold columns. Many attempts to find this cave north of Beaver cave. Hides someplace in the Salal bushes. So named by Jim Neiland. 

 Sand Cave: This cave is now buried by sand from Mount Saint Helens, sometime after 2006. Was a nice little cave that had ice formations in it.Other names. Knight's cave and Camp cave. Story Speleograph 381 with map and pictures.

Discovered in 1966 by an Oregon Grotto member named “Doug”, the main entrance is at the south end of a large sinkhole at the base of a steep basalt slope. In 1972, the known cave was about 220 feet long.  In 1984 it was noted that the entrance sink had filled with colluvium (chiefly pyroclastics from the 1980 eruption of Mount St. Helens),  reducing the cave to a total length of approximately 65 feet, eliminating the skylight. 

  Scott's Cave: A complex cave system with lot of neat features and entrances. Lots of crawly.

 Utterstroms Caves are a disorderly series of six small named caves and even shorter unnamed tube segments, north of McBride Lake Road, well north of Little Red River Cave. Located in a steep section of the Cave Basalt Flow, they are highest known caves in the Cave Basalt (#0914). Lowest of the series is Breakdown Cave, followed upslope by Moss, Railroad Track, Surprise, Arch, Lava Spring and Pats caves. All but Breakdown Cave are shallow (near the surface), and they lack the characteristics of the larger, deeper caves like Little Red River. Breakdown Cave, associated with an anomalously large and deep collapse sink, perhaps shouldn't be considered part of the series.
   Discovered by Bill Reese and Cascade Grotto member Jan Utterstrom, first described by Bill Halliday following a June 1963 visit.

 What Cave: This small caves found many years ago mapped and explore Oct 2011 to about 200 feet of mostly crawly cave. Has two lava intrustions, a small side passge and a large chamber about 7 feet high. Three  entrances in the breakdown sink. AKA as Tadepole cave.
