Tips from the Community
Although it is known and named as a geyser, the Terminal Geyser is more like a steam vent than a true geyser. That does not make it less impressive. To get here, you have to follow a narrow, sometimes not that obvious trail. You can even climb down all the way to the steam that reveals a certain smell like rotten eggs. Always be careful around hydrothermal areas!

"For your safety, stay on established trails and boardwalks. Ground in hydrothermal areas can look solid but may actually be a thin crust hiding pools of acidic boiling water or mud. Traveling off-trail in these areas may result in severe injury. Read more about exploring the park hydrothermal areas." https://www.nps.gov/lavo/planyourvisit/hiking_terminal_geyser.htm

Basin fens originated as lakes or ponds and formed as the pond was filled with partially decomposed plant remains. Basin fens are typically flat and occur near or on the margin of open water. Basin fens are widespread in North America and may be quite large, such as surrounding Domingo Lake https://www.fs.usda.gov/wildflowers/beauty/California_Fens/types.shtml

The Mount Harkness Fire Lookout sits on the summit of Mount Harkness. The lookout has been in operation since its construction in 1930. Seasonal staff stationed at the lookout continue the vigil today and are often available to answer visitor questions and demonstrate fire lookout techniques. At an elevation over 8,000 feet, Mount Harkness provides excellent views of the park and distant mountain ranges.

Take the loop or hike at least along the east side of the pond. Here are the most existing geothermal activities like bubbling mudholes and steaming soil. The mudholes are not visible from the west shore.

There is lots of space for tents around Boundary Spring - however this is a very badly burned area with lots of dead trees that will fall itself or you might be hit by falling branches. My advice to reduce the risk: Get your water from the spring, hike on into Lassen National Park for ~ 0.2 miles, turn left onto the Willow Lake Trail, follow the faint trail for another ~ 0.3 miles to the trailhead. There is room at the dead end and you will be outside the park boundary again.
