About this map

Summertown and the surrounding volcanic terrain define this 2021 study of the northern reaches of Lassen Volcanic National Park. The map documents a complex landscape of geothermal and geological significance, centered on the waters of Manzanita Lake and Reflection Lake. The southern portion of the sheet is dominated by the stark formations of Chaos Crags and the Chaos Crater, providing a detailed look at the area's explosive history.

Historical transportation routes are clearly marked, tracing the path of the Nobles Emigrant Trl and the older Emigrant Road as they navigate the passes. Significant landmarks for local history and navigation include Noble Pass, Eskimo Hill, and Ashpan Butte. To the north, the terrain transitions into the Lassen National Forest, where the topography rises toward Grayback Ridge and the volcanic prominence of Red Mtn.
