2019 Lassen Geology
Instructor: Chas Rogers, M.S. Dates: Friday-Sunday, August 2-4, 2019 Location: Meet at the Loomis Museum inside the west entrance to Lassen Volcanic National Monument Tuition: $165
Lassen Volcanic Field contains a variety of landscapes unique to the Pacific Northwest. With its high peaks, mountain lakes, hot springs and mud pots, and numerous volcanic flows, Lassen encompasses many geologic features of the Cascade Mountains. This field trip contains a little of all these features and more. The domes, collapsed calderas, and glacial valleys compose a magnificent landscape populated by vibrant wildflowers and animal life. We will meet at the Loomis Museum Friday afternoon to view the geologic history displays, then hike either the Chaos Jumbles or Cinder Cone at the north end of Lassen Volcanic National Monument. Saturday the group will climb Lassen Peak (moderate hike with a 2,000 ft. elevation gain from the trailhead). On Sunday, we’ll hike the Bumpas Hell trail to view hot mud pots and volcanic hot springs. As we depart Sunday afternoon, we’ll study the Lassen caldera from several stops along the highway.
