This classic route is also know as the Squamish-Cheakamus divide traverse. The trip describe here goes from Brew Mountain to Callaghan Lake, but many variations are possible. The route can be extended south to Tricouni Meadows, or north onto the Pemberton Icefield. There are also access/escape points along the way from Brandywine Creek, Callaghan Valley or the Squamish River. Note that most of the traverse is through snowmobile territory, so machine traffic is the norm when traveling along the divide. Most snowmobiles access the area from Brandywine Meadows and Tricouni Meadows; skiing these access routes on a busy weekend would be rather unpleasant. Other access routes (Roe Creek, Callaghan Valley, Shovelnose Creek) are more or less snowmobile free by comparison.

Access

There are many access points at various places along the divide. They are listed here from south to north

• High Falls Creek gives access to Tricouni Meadows and Seagram Lakes. Reach the alpine near Cypress Peak and continue north along the divide.
• Roe Creek logging road gives access to the Brew Hut, or more directly to the divide just north of Cypress Peak.
• The West fork of Brandywine Creek provides access to the Brew Hut, or up the valley bottom to reach the divide between Cypress Peak and Mount Fee
• A branch of the Squamish River road system climbs up near Mount Fee
• Roads in Brandywine Creek climb close to Brandywine Meadows. Access from here goes up past Brandywine Mountain to reach the divide
• Callaghan West FSR (Reached from Callaghan Valley Road) can be skied to it's end below Metal Dome, then traverse the valley bottom around the north side of Brandywine Mountain. Access the divide at the bowl S of Powder Mountain
• The Creek NE of powder mountain can be reached from the Wild Spirit XC trail in the Callaghan Valley. Park at Alexander Falls on the Callaghan Valley Road.
• The main access to north end of divide is via Callaghan Lake and the NW branch of the Callaghan Valley. Park at Alexander Falls on the Callaghan Valley Road. From there, groomed XC trails lead up the NW branch of Callaghan Creek.

Route

The route can be divided into 4 sections:

1. Ascent to Brew Mountain Cabin. The standard route these days is from Roe Creek. Approaching from Brandywine Creek is still possible as well.
2. The traverse of the Brew Divide and thence north along the main divide, passing Mt. Fee on its west side. Parties can avoid the steep narrow ridge 2 km south of Fee by dropping down to gentler west slopes via a shoulder to the south, and skiing near tree line. Access to the Cayley icefield is best through a Col 1km east of the head of Shovelnose Creek. In the creek, slopes are steep and the Glacier crevassed.
3. Powder Mountain ice cap, straight-forward glacier travel.
4. Descent to Callaghan Valley - once in the valley bottom pick up the groomed XC trail network. Follow these trails back to Alexander falls, via Callaghan Lake or by the more direct Wild Spirit Trail.

Hazards

1. Many potential avalanche slopes must be traversed.
