Bear Creek

Bear Creek is one of the named water crossings on the John Muir Trail, sitting at roughly mile 97 southbound from Happy Isles (or about mile 124 northbound from Whitney Portal), just below Rosemarie Meadow in the headwaters of the South Fork San Joaquin River. In a normal July it is a straightforward knee-to-thigh wade. In heavy-snow years it is one of the most dangerous fords on the JMT and PCT — experienced reporters have described a fall at peak runoff as near-certain fatality.

Geography. The crossing sits between Bear Ridge Junction (mile ~92.6 SOBO) and Marie Lake (mile ~100.7), below the final climb to 10,900-foot Selden Pass. Southbound hikers reach it after the long climb out of Quail Meadows and Vermilion Valley Resort. Northbound hikers drop into it from Selden Pass via Rosemarie Meadow. The creek at this point is gathering drainage from the Hilgard Branch and from the basin above Marie Lake — a large watershed that responds dramatically to diurnal snowmelt.

Typical character (mid-July through September, normal years). A 25–40 foot crossing of cold, clear water running knee to mid-thigh, with a rocky bed and moderate current. Most parties cross in 2–5 minutes using trekking poles planted upstream. Stepping stones appear in low-water years. There is no bridge at the main trail crossing and no consistent single log — conditions change year to year as logs shift. The crossing is exposed and there is no obvious eddy to recover in if you fall; the current carries downstream into rockier water.

Peak character (late-May through early-July, and into August in heavy-snow years). The ford becomes waist- to chest-deep with powerful, opaque current. During the record 2017 snowpack, multiple trip reports described the main JMT/PCT crossing as impassable at peak flow, and the overwhelming majority of PCT thru-hikers bypassed the Bear Creek section entirely that year. Bear Creek is often rated less extreme than Evolution Creek (which has documented fatalities) but more serious than Mono Creek (which is bridged in most years). Treat any chest-deep reading as a turn-around condition, not a cross-with-care condition.

The downstream log crossing. About 0.3 miles downstream from the trail ford — the point marked on this page as the alternate — Bear Creek splits around a small island and a large fallen tree spans the far channel. Hikers have marked the junction with cairns and a scratched-dirt "LOG" arrow pointing downstream; a visible use trail runs from the riverside meadows directly to the tree. The near channel at the island is calf- to knee-deep in normal conditions and is often the shallowest line at the ford regardless of year. Alternatives further afield — the upstream Medley Lakes routing, which reaches the South and East Forks independently, and the Bear Ridge Trail / Vermilion Valley detour — exist but add miles and are beyond what most JMT itineraries accommodate.

Decision framework. In a light- or normal-snow year after mid-July, take the main trail crossing. In a heavy-snow year or before the July Fourth weekend, walk 0.3 miles downstream to the log before getting wet. If the main crossing reads waist-deep and the current feels like it can take your legs, do not attempt it solo — retreat to the log, wait for morning, or turn back to VVR and reroute via the Bear Ridge Trail. Bear Creek has been the decision point where more than one JMT itinerary has ended safely by choice.
