Sound By Nature

This was recorded on a cloudy night in early autumn in a stand of Quaking Aspen near the South Fork of Emerson Creek in the South Warner Wilderness, Modoc National Forest, Modoc County, California. The night was cool, and gentle breezes rustled the leaves of the Aspens throughout the night.
Listen for the sound of a lone elk bugling just past the one minute mark.

This was recorded on a calm summer night beside Sugar Creek in the Sugar Creek Research Natural Area, which is located within the Russian Wilderness, Klamath National Forest, Siskiyou County, California. The creek flows down the east side of the Salmon Mountains, a subrange of the Klamath Mountains, in far northern California. The creek was low for this time of year, owing to a meager snowpack that had already melted entirely.
The Sugar Creek Research Natural Area is a unique and special place. According to the U.S. Forest Service it was created "primarily to preserve the richest known assemblage of conifers in the world", in an area that has "essentially remained unchanged by humans since before the European colonization of California".

This was recorded on a cold, cloudy, and breezy summer morning in the Salmon Mountains near the Music Creek Trailhead in Klamath National Forest, Siskiyou County, California.

This was recorded on a clear spring night under a full moon beside Summit Meadow Lake in Marble Mountains Wilderness, Klamath National Forest, Siskiyou County, California. I recorded this tree ears style, in which a mic is placed on either side of the trunk of a tree, in this case a Red Fir. Though I recorded all night, this part of the recording is from the wee hours of the night when the frog chorus was starting to die down.

This was recorded on a cold and breezy spring morning near an unnamed pond on the east side of the Trinity Divide in Shasta-Trinity National Forest, Siskiyou County, California. The recording starts a little after 4 a.m., and a little before the birds began their dawn chorus.
