Tumuli Lava - A Backdoor into the Badlands

What are tumuli (besides the plural of tumulus)? From the Latin tumidus, meaning swollen or bulging in shape, a tumulus is a circular, domed lava structure up to 30’ high and 60’ in diameter, formed by the upward pressure of actively-flowing lava against its cooling crust. Along with its elongated cousin, the pressure ridge, these fascinating lava formations can be explored on a less-traveled trail in the Badlands Wilderness, just 15 miles east of Bend.

Pioneer Wagon Road at McKenzie Pass

In the late 1800s, Central Oregon was not an easy place to reach from the Willamette Valley. Though there was great demand for access by stockmen, who desired to drive their cattle east into the vast bunchgrass plains, the Cascade Range was impassable in winter and the few established trails were difficult and dangerous. That is, until John Templeton Craig pioneered a wagon road across the lava fields at McKenzie Pass — a route that can still be enjoyed today by adventurous hikers.

Kipukas - Forest Islands in a Sea of Lava

One of the more interesting geologic features of Central Oregon are kipukas (meaning “a variation or change in form” in the Hawaiian language). These are islands where lava has surrounded patches of older terrain, isolating them from the surrounding landscape. It’s hard to imagine a more dramatic contrast between the dry, rocky, barren fields of lava surrounding the relatively moist, shady islands of forest.
