Most people who finish the 2,650-mile Pacific Crest Trail come home with a memory card full of photos. Tom Kelly came home with hours of sound. The LA-based hiker, composer and nature sound field recordist thru-hiked the PCT in 2023 carrying about 40 ounces of audio gear on top of everything else, stopping to record whenever the trail offered something worth hearing.
What he captured is the trail in a way pictures can't convey: creeks burbling, insects chirping, grass moving in the wind, rain drumming on a tent fly, other hikers chatting as they pass. After finishing the hike, Kelly spent two years turning the recordings into an interactive sound map that anyone can use for free.
His process required real discipline. He describes waking at a lake to a great horned owl calling across the water, and the effort it takes to get up, grab the gear, hike to a spot and set up a recording before the moment disappears. One of his favourite sessions happened in the Mojave Desert, on the north side of the LA Aqueduct — he simply sat down, switched on the recorder and listened. That, he says, was the moment the project clicked: a tiny, deep experience set against the scale of a massive trail.
Kelly sees the map as a gift rather than a document. He wants listeners to slow down and get a small piece of what thru-hikers experience — the quiet, the wind, the layers of natural sound that most of us miss on a normal day. For anyone who can't take five months off to walk from Mexico to Canada, it's probably the closest you can get to standing on the trail without leaving home.
Why it matters: the PCT runs through desert, old-growth forest and high alpine country, and sound is a big part of what makes each section distinct — the dry silence of the Mojave, cicadas in Oregon, wind on a ridgeline in the Cascades. Armchair hikers planning a future trek can use the map as a preview of each region's atmosphere, and people considering a section hike might find it changes where they want to go. It's also a free, zero-effort way to bring a bit of wilderness into a workday, and a nudge to record your own next trip differently — bring headphones or a recorder, not just a camera.
