Pacific Northwest Trail Snow Conditions - Dec 13, 2018

Below you will find detailed and current Pacific Northwest Trail snow conditions for the entire trail. This is not a 'snow pack' chart. This chart shows 'trail snow'. 'Snow pack' and 'trail snow' can differ significantly. Where the PNT traverses the highest terrain, the PNT snow conditions will almost always exceed snow pack.

Snow pack is not trail snow.

'Snow pack' is determined from relatively few physical snow sensors covering an entire mountain range of which most are not on or near the PNT. For instance, the previous postholer snow page relied on about 2 dozen sensors across thousands of miles of trail. Much of the PNT has no sensors, thus no coverage.

The charts here rely entirely on data from SNODAS modeling from NOHRSC/NSIDC. For example, the PCT has 5,300+ data points and the CDT 6,000+. Each trail has a point every half mile/within a half mile of the trail or better. This is a huge improvement in accuracy of PNT snow conditions. These snow graphs allow you to view the PNT in a way no one has before.
