Twin Sisters Rock
It’s amazing that on October 18, 1805, the Lewis and Clark Expedition passed by—and camped just below—Twin Sisters Rock without specifically mentioning it in any of the journals. Clark was in awe of the cliffs engulfing both sides of the Columbia River in present Wallula Gap:
“the Countrey rises here about 200 feet above The water and is bordered wth black rugid rocks”
—William Clark
Today, the short climb to the base of the rock is worth the time and provides an excellent view of Columbia River meandering through Wallula Gap. The hike is about a one-mile round trip.
Twin Sisters Rock is a basalt formation shaped by the Missoula floods about 10,000 to 20,000 years ago. At the trailhead, there is a sign telling the Native American legend of the two sisters. Social trails lead onto private land, so stay on the main trail. By County Ordinance climbing is not allowed on the rocks.
