Route Description

Follow the well maintained Phantom Creek Trail from Alpine, Montana towards the pass between Froze to Death and Saddleback mountains. As the trail begins to climb out of the valley you will encounter the first switchback. It is here that you will find a faint climbers trail which continues up the Phantom Creek Drainage towards Mount Peal. The "trail" leads up over some boulders and considerable loose scree before arriving at Phantom Lake. Several good campsites can be found near the lake. There are no trails beyond this point.

From Phantom lake continue up the valley towards Froze-To-Death lake, staying on the North side of Phantom Creek. There are some faint goat trails in places which can be followed to make the climb to the next lake a bit easier (class 2). Circle around the North side of Froze-To-Death lake to avoid steep cliffs and loose scree on the South side of the lake.

Mount PealLooking at Peal from Turquoise Lake, Brent lake is at the base of the moraine below the snowfield in this picture.

Cross over Phantom Creek between Froze-To-Death and Turquoise lakes (easy rock hopping) towards Brent lake. From Brent lake you will climb up the moraine towards the lake at the base of the permanent snowfield on the East side of Mount Peal. The traverse around this lake is time-consuming, and involves some 3rd class scrambling over large boulders. Once on the glacier / snowfield strap on the crampons and make your way towards the saddle between Peal and Pleasant on the summit plateau. The angle of the glacier increases towards 45 degrees towards the top, and there are a couple of tension cracks near the top which may be hidden early in the season.

For those without crampons the easiest way to get to the summit plateau will be to follow the scree covered left (South) side of the glacier. Near the top the angle increases significantly, and the rock overlying the snowfield is dangerously loose and prone to sliding.

The difficult part of the climb is over once the plateau is reached. Once on the plateau stroll North West towards Peal's summit.

Essential Gear

The safest way to reach the summit plateau is to stay on the Peal Glacier. A Ice Axe and Crampons are needed. A Helmet would be wise if you plan to attempt the climb of the scree covered South side of the Glacier.
