1995 Map of Poison Lake

About this map

Poison Lake and the volcanic landscape of Poison Butte dominate this section of the Lassen National Forest during the mid-1990s. The region is defined by forestry research and land management, centered around the Blacks Mountain Experimental Forest and the State Game Refuge. Evidence of industrial history is visible in the Old Railroad Grade that winds through the northern timberlands, while several Cinder Pits and a Quarry suggest active resource extraction near the volcanic peaks. The presence of Longs Cabin and remote water sources like Robbers Spring and Patterson Well highlights the sparse, utilitarian nature of human settlement in this high-elevation basin. The landscape is further marked by modern utilities, including a single wooden pole power line following the Pittville Road.
