Limestone rock wall pattern—fossilized Triassic reef uplifted 9000 feet on the Matterhorn, Wallowa Range, Oregon, USA.

This rock wall pattern contains a fossilized Triassic reef and volcanic rocks that were uplifted 9000 feet above sea level within the Sacajawea-Matterhorn cirque in the Wallowa Mountains, Wallowa–Whitman National Forest, in the Columbia Plateau of northeastern Oregon, USA. The Matterhorn of the Wallowa Range is composed of limestone of the Martin Bridge Formation. From Wallowa Lake Trailhead, I hiked 7.7 miles one way with 3200 feet gain to Ice Lake plus 3.7 miles round trip with 2000 feet ascent and descent to Matterhorn Peak. I tented overnight at Ice Lake before returning 7.7 miles to the trailhead.
