World Listening Day was spent at Lassen Volcanic National Park! We shared some sounds of the Park with interested visitors and had a great reception. Thanks to the rangers and other volunteers for their support and hospitality.

Didn’t escape without recording though, here is a little snippet of Pirate’s Pool at the Bumpass Hell:

Dream Lake & Boiling Springs Lake

Saturday, May 2nd, 2015

Some of you know that I’ve been making some recordings for the National Park Service at Lassen Volcanic National Park. Over the next few weeks I will start posting some snippets of what I have found.

Dream Lake (above) is an area that has been under restoration since the man-made dam was removed in 2011. As the water drained several streams that fed the historic lake converged to form a new habitat.

Boiling Springs Lake (above) represents the prime call of what Lassen Volcanic Park is known for: bubbling, gurgling, hydrothermal features.  This is a good example of what Bernie Krause calls “geophony”.

Apologies for a missed opportunity this post: in our haste to get to Lassen Volcanic National Park for a much needed weekend getaway we left the camera at home so you will just have to visit on your own or look around here.  Well the weekend getaway nature of this trip put recording on the back burner but it was a good opportunity to scout the area before lugging recording gear in…but I decided to lug gear anyway.  We headed out from the Warner campground, a dusty national park campground that seems lightly visited, it’s just a mile or so from the trailhead to the lake itself.

I situated the mics and myself between two bubbling mudpots, much to Nicole’s concern and encouragement.  There were plenty of other footprints where I was setup so I wasn’t too worried, though I did notice that the ground was physically warmer in some places, weird.  Shortly after hitting “record” a curious couple spent a long time exploring the relatively small area frequently calling out to find the other.  A Spotted Towhee was foraging in the area some calls and wingbeats can be heard..

UPDATE: I decided to mix and post my recording at Terminal Geyser, which is not really a geyser but a steam vent, at first it was a little boring to listen to but once I mixed in the 154° (67°C) bubbling stream I decided it was worthy:
