The Forest Service Scott Paul Trail 603.1 (formerly Sulphur Moraine Trail) shares the TH with the Park Butte Trail 603. Take the first right (100') down the trail and begin easy climbing N through forest for 2 miles up a broad shoulder (staying right - E of) a prominent creek drainage. In early spring the trail can be lost just keep in mind to maintain your direction (N) with a creek on either side of you. At about 2 miles (from the TH) the Scott Paul Trail diverges (left - W) from the climbers route which continues up and N. Continue hiking N reaching the Glacier at around 6200' elevation. Camping is allowed above 6000' (FS rules) but a high camp site (6960') can be found alongside the Sulphur Moraine (right-hand edge of the glacier) or below a Prow of rock (due N) at 7680'. This Prow is clearly seen (on the S skyline) from a distance to the SW. From high camp skirt the rock Prow to the W and then continue N to below a small horn on the Sherman Crater rim half-way between Sherman Peak and the Roman Wall; near to the N of here is where the Easton and Squak routes merge (see photo). Negotiate the short steep slope to the crater rim and continuing (N), climb the final steep slope up to the summit plateau; stay left (W) of the Crater (and rock wall above it) and right (E) of the Roman Wall. Grant peak is the small hump on the NE corner of the plateau. Descend the route.
