This was recorded on a pleasant fall day beside the North Fork of the Salmon River at the Mule Bridge Trailhead in Klamath National Forest, Siskiyou County, California.

This was recorded on an autumn afternoon by East Boulder Creek in Trinity Alps Wilderness, Siskiyou County, California. Where I recorded this the creek flows through a steep gully, so I placed the mic at the edge of the gully above the creek, but not very far from it. It was a cold day, and at the start of the recording it was cloudy with occasional light snow flurries. But by the end, the clouds began to part and let the sun light through.

The area received its first snow of the season the night before, and though it had almost entirely melted at the recording location, there was still a thin layer of snow coating the ground further up in the mountains. While this was recording I hiked up to East Boulder Lake, continued past the three small lakes above it, and up over the ridge to the intersection with the Pacific Crest Trail. It was my first time visiting this part of the Trinity Alps Wilderness, and it was a real treat to get to leave my footprints in the first snow of the season.

This was recorded on a stormy summer night beside a small pond in the forest east of Black Fox Mountain in Shasta-Trinity National Forest, Siskiyou County, California.

I placed the microphone beside the pond in order to capture the sound of the raindrops hitting the water. I then covered the microphone and tripod with pine needles to prevent the rain from hitting them directly, which would cause unwanted sounds. I think it worked very well.
