Elevation: 8,753 ft
Climbing and access information for this peak is on Page 147 of the book.
Tyee Mountain is seldom visited despite the fact that there is high elevation access to its slopes via FS-312. While the peak is a long way from a paved road, access is good at least in a relative sense. FS-312/Graham Road is a long, winding road which eventually leads to the upper reaches of the North Fork Boise River. It provides the best access. Take ID-21 from Boise for 55 miles to the turn for FS-384 at the [signed] Edna Creek Campground turnoff. Turn onto the excellent FS-384 gravel road and follow it to FS-312 in 4.0 miles. FS-312 is a good road but is not recommended for passenger vehicles.
The main intersections are signed for Graham Road. The road crosses a pass between Archie Mountain and Peak 7561, continues to another pass and a junction with Jackson Peak Road, and then descends into the upper reaches of Crooked River. The road climbs out of the Crooked River drainage to yet another pass at the base of Peak 8498. Continue on the road past this peak to the next pass. From this point, you can follow the ridge east to the summit. I have yet to follow the route but it looks to be Class 2. USGS Tyee Mountain
