Activity Notes

We will meet at the Bonneville Trailhead for an out and back hike to Aldrich Butte, a lesser and less-visited butte in the Columbia Gorge that sits in the shadow of Table Mountain. Most of the hike occurs on the PCT as it makes its way north away from the Columbia River and around Table Mountain. As such, it is a good spring hike to knock the rust out without gaining too much elevation.
