Limestone & volcanic rock patterns on Sacajawea-Matterhorn Ridge, Wallowa Mountains, Eagle Cap Wilderness, Oregon, USA.

The Sacajawea-Matterhorn Ridge displays a motley mix of limestone (fossilized reef) and volcanic rocks of the Martin Bridge Formation, in the Wallowa Mountains, Wallowa–Whitman National Forest, in the Columbia Plateau of northeastern Oregon, USA. 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.
