Tumalo Mountain

Tumalo Mountain is a shield volcano in the Cascade Range that rises prominently above the surrounding terrain in central Oregon. Its northeastern flank displays notable glacial formations that shape the mountain's appearance and create distinctive geological features.

The summit once held a fire lookout tower that served the region for decades during the mid-1900s. This structure was part of a broader forest monitoring system that has since been abandoned.

The mountain holds geological importance within the Cascade Volcanic Arc, contributing to scientific research of volcanic formations in Oregon.

The summit is reached via established trails on the southwest side that offer steady access to the peak. These paths provide views of neighboring volcanic peaks and the broader mountain landscape.

The glacial cirque on the northeastern flank creates a natural bowl that attracts backcountry skiers and winter visitors. This geological formation transforms the peak into a winter sports destination for experienced adventurers.
