Pattern of limestone & volcanic rocks in Sacajawea Peak, Wallowa Mountains, Eagle Cap Wilderness, Oregon, USA

Sacajawea Peak displays a motley mix of limestone (fossilized reef) and volcanic rocks of the Martin Bridge Formation, lit here at sunrise, in the Wallowa Mountains, Eagle Cap Wilderness, Wallowa–Whitman NF, 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 in the Wallowa Mountains, Eagle Cap Wilderness, Wallowa–Whitman National Forest, in the Columbia Plateau of northeastern Oregon, USA. I tented overnight at Ice Lake before returning 7.7 miles to the trailhead.
