2012 Map of Boulder Peak

About this map

Boulder Peak and the surrounding Marble Mountains define this high-elevation landscape in Siskiyou County, where water resources dominate the terrain. A dense network of alpine lakes, including Upper Wright Lake, Lower Wright Lake, and the tucked-away Wolverine Lake, are fed by numerous seasonal drainages like Shackleford Cr and Mill Cr. This 2012 survey illustrates a wilderness area structured by elevation and moisture, with features like Sniktaw Meadow and Big Meadows providing clearings within the timbered slopes. The presence of Mill Creek Ponds and larger bodies like Isinglass Lake suggest a complex hydrology that supports the local ecosystem. Primitive access routes such as Forest Rte 43N23 and Smokey Ln provide the only human-engineered entries into this backcountry, emphasizing the area's role as a protected natural watershed near Red Mountain.
