If you study a topo map of the Snoqualmie Pass area, you will find that this region has a rugged relief rather uncharacteristic of the North Central Cascades. Just a few miles north of the pass are glaciers larger than those of the Stewart Range. The peaks north of Snoqualmie Pass (with the exception of the Lemah and Chimney Rock massif) may not hold a summer mountaineer's attention for too long, but winter adds the needed alpine element to make these mountains superb ski-mountaineering goals.
