Left Corner Wall

Left Corner Wall is a climbing area on county land in Oregon, managed by Clackamas County. It sits within Clackamas County's own county facility or land, about 7.5 miles from the town of Oregon City. The climbing is close to several other walls, with Orange Wall and Fourth Class Wall each about 0.1 mile away. The routes here run from about 5.9 to 5.12a on the YDS scale, and the climbing is a mix of trad and sport. Trad routes make up most of the options, with sport routes like Verbal (5.11a) and Talk, Talk, Talk (5.12a) standing out. The most experienced climbers will find Talk, Talk, Talk, a sport route at the top of the range, while Patrick's Dihedral (5.9) is a trad option that's easier to get on. The most comfortable months for a visit are typically late spring and early fall. At a nearby weather station in Oregon City, typical averages run to highs around 71°F in May and 78°F in September, with summer highs in the mid-80s. Winter is cool, with typical January highs near 48°F and lows around 37°F. For more time on the county's trails, Cazadero Trail is about 3 miles away and the East Buttes Power Line Corridor Trail is roughly 4 miles off. Paddlers can head to Abernethy Creek, about 6 miles away, or Deep Creek, just beyond it.
