About This Route
Evolution Creek in Kings Canyon National Park flows through the Evolution Valley, a PCT highlight from Muir Trail Ranch to LeConte Canyon. Thru-hikers tackle this 12-mile section with multiple fords, especially at the Evolution Creek crossing near mile 225 southbound, notorious for thigh-deep to chest-deep water during snowmelt. While primarily a ford, opportunistic swims occur in pools above the crossing. NPS rangers label it the PCT's most hazardous water feature; high snow years like 2023 saw multiple evacuations. Surrounding granite slabs and meadows make it scenic, but safety trumps temptation.
Safety Considerations
Peak flows in late June hit 1,000 cubic feet per second, creating hydraulic holes that trap swimmers, per USGS data. Unbuckle your backpack hip belt before entering, as advised by PCTA forums and Gail Storey's accounts, to swim free if swept downstream. Water temps hover at 40 degrees Fahrenheit, inducing cramps; test depth and current first. Avoid crossing or swimming solo; use ropes belayed by partners. Afternoon thunderstorms swell creeks rapidly; start early. Follow NPS high water protocols: wait for flows under 300 cfs via sierrahydrology.com.
Essential Gear
Crocs or Chacos sandals for grip on slick granite. A throw rope from REI or Black Diamond for group safety. Sandbags or closed-cell foam for flotation under packs. Quick-dry synthetic layers and a wool hat combat post-swim chill. Garmin inReach for remote SOS.
Emergency Tips
If pinned in a hydraulic, relax and swim downstream aggressively on release. For foot entrapment, signal partners to throw rope. Hypothermia protocol: huddle with group, share dry clothes, descend to McClure Meadow. Contact Sequoia-Kings Canyon NPS via satellite.
