Lava Flow and Vine Maples

The Proxy Falls Loop Trail offers a unique geological and botanical experience as it traverses an old lava flow colonized by vibrant vine maples. This ancient volcanic landscape provides a stark contrast to the surrounding forest, with hardy shrubs like vine maple, chinquapin, and cascara thriving in the rocky terrain. The trail’s journey across this lava field not only showcases the area’s volcanic history but also treats hikers to a spectacular display of fall colors when the vine maples turn brilliant shades of red and orange.

Lava flow adds geological interest to the hike
Vine maples and other hardy plants have colonized the volcanic rock
Stunning fall foliage display, especially from the vine maples
Trail offers views of nearby cliffs and peaks from atop the lava field
Transition between lava field and dense forest highlights ecological diversity

Upper Proxy Falls Disappearing Pool

Upper Proxy Falls, a 130-foot cascade, features a fascinating natural phenomenon at its base. The water plunges into a mysterious pool with no visible outlet, seemingly disappearing into the earth. This vanishing act is due to the porous lava rock beneath the pool, which allows the water to seep through and continue its journey underground.

Pool at the base has no visible stream flowing out
Water seeps through porous lava rock into the ground
Accessible via a side trail off the main Proxy Falls Loop
Surrounded by a cool forest chamber with tall trees
Less photogenic than Lower Proxy Falls, but offers a unique geological spectacle

Glacially Carved Proxy Creek Canyon

The Proxy Falls area showcases a dramatic landscape shaped by glacial activity during the last ice age. Approximately 20,000 years ago, glaciers descended from the Three Sisters, carving out the White Fork valley and scooping a deep canyon at the bottom of Proxy Creek. This glacial action created the steep cliffs over which Proxy Falls now cascades, with the 225-foot Lower Proxy Falls being the most impressive result of this geological process.

Valley carved by glaciers from the Three Sisters about 20,000 years ago
Glacial retreat around 6,000 years ago left behind the deep, scooped-out canyon
Lower Proxy Falls drops 225 feet over glacially-carved cliffs
Hanging valley formation contributes to the falls’ impressive height
Subsequent lava flows about 1,500 years ago further shaped the landscape, creating porous ground that allows some streams to flow underground
