Soon this sign will be covered in the snow which will close the road through Lassen Volcanic National Park.

Bumpass Hell is located near the park’s SW entrance and is a popular hike despite the moderately steep trail at 8,000 feet (2400 m), the gritty gusty wind and the ‘rotten egg’ smell.

Named for early guide and miner Kendall Vanderhook Bumpass, “…Bumpass Hell is the largest hydrothermal area in the park, and marks the principal area of upflow of steam and discharge from the Lassen hydrothermal system….  Please stay on the trail and boardwalks for your safety.”

The trail is 1.5 miles long and takes at least an hour and a half. Bring water.

Yellow color indicates sulphuric compounds.

“The temperature of high-velocity steam jetting from Big Boiler, the largest fumarole in the park, has been measured as high as 322°F (161°C), making it one of the hottest fumaroles in the world. The steam heated waters are typically acidic and are not safe, even for bathing.”

Lassen Peak, with it’s weird medallion rock face, lords it over the park.

Can you tell from which direction the ice sheet(s) came kids?

Time to head for warmer climes.
