Geology
The park is within the Cascade Range and [[The park is within the Cascade RangeModoc Plateau natural region, with 910 acres (4 km²) of forest and five miles (8 km) of streamside and lake shoreline, including a portion of Lake Britton.
The park's centerpiece is the 129 foot (39 m) Burney Falls, which is not the highest or largest waterfall in the state, but arguably the most beautiful. Additional water comes from springs, joining to create a mist-filled basin. Burney Creek originates from the park's underground springs and flows to Lake Britton, getting larger along the way to the falls.
The park's landscape was created by volcanic activity as well as erosion from weather and streams. This volcanic region is surrounded by mountain peaks and is covered by black volcanic rock, or basalt. Created over a million years ago, the layered, porous basalt retains rainwater and snow melt, which forms a large underground reservoir.
Within the park, the water emerges as springs at and above Burney Falls, where it flows at 100 million gallons every day (4.4 m³/s).
