Rocky Reach Dam
Petroglyphs inside interesting museum.
Take Hwy 2 all the way to the Columbia river and then go south along the river until you see the signs for the dam. You now are on the wrong side of the dam so you must go further south a few miles to the next bridge and cross it to the west side and then go back north to the dam and follow signs to the museum. This museum is free and fun to go through as it is underground inside the dam structure.
