Read the transcript
Upstream from here is Big Creek. Downstream is Glacier Rim.
Drive 7.3 miles north from the intersection of the Blankenship and North Fork Roads, then turn right.
The parking area is packed dirt.
There is no designated accessible parking.
The route from the parking area to the river averages 3 percent grade, steepening to 25.9 percent at its steepest point.
Cross slope, the sideways tilt that matters most in a wheelchair, averages 3 percent, with a maximum of 7.6 percent.
The path averages 8.3 feet wide, narrowing to 3 feet at its tightest.
Underfoot it is 75.6 percent hard, and 13.1 percent firm.
You drop about 11.5 feet on the way down to the water.
The launch itself is unimproved ramp dirt slope, cobble shore.
What to watch for, in the survey crew's own words:
No vehicle and trailer access to water level. Users must carry or drag watercraft on highly uneven footing down the hill to water level.
Facilities: Vault toilet.
Conditions on the Three Forks change quickly. Check the gauge the morning you float.

The site

Curated RAPG fields are interpreted from the FRA access sheet and its photographs; sequence evidence summarizes only the assigned panoramas. Conditions may extend beyond every photographed view. FRA’s field measurements in the Measured access card remain the authority for access type, grades, widths, surfaces, gaps, and accessible parking.
