Upstream from here is Ford. Downstream is Polebridge River Access (Upstream).
Drive 32.9 miles north from the intersection of the Blankenship and North Fork Roads. Turn right onto Sonderson Access Road. Access is on the left in 1.2 miles.
The parking area is packed topsoil.
There is no designated accessible parking.
The Flathead Rivers Alliance has not published measured survey data for this site yet, so the details that follow come from the site description rather than from field measurements.
The launch itself is undeveloped.
What to watch for, in the survey crew's own words:
No ramp or slide system to assist users with transporting watercraft to the river.
Crumbling social trails down steep, erosive cobble cutbanks to an uneven and complex bouldered bank. These trails include vertical steps of >1 feet.
Poorly sorted, rounded stones at water level are unstable and
frequently shift under foot.
There are no facilities at this site.
This site has not been photographed in 360 yet, so there is no immersive imagery to accompany this description.
Conditions on the Three Forks change quickly. Check the gauge the morning you float.

The site
