Pacific Crest Trail Snow Conditions

Snow page updates between November 1st and June 28th.

Below you will find detailed and current Pacific Crest 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 PCT traverses the highest terrain, the PCT 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 PCT. For instance, the previous postholer snow page relied on about 2 dozen sensors across thousands of miles of trail. Much of the PCT has no sensors, thus no coverage.

The charts here rely enitrely on remote sensing data from 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 PCT snow conditions. These snow graphs allow you to view the PCT in a way no one has before.

Sierra Entry Indicator - The SEI is to help you determine what snow conditons are like north of Kennedy Meadow. This looks at hundreds of locations between Kennedy Meadow and Reds Meadow (210 miles) and gets the percent of average snow conditions. The SEI updates from Nov 1 to Apr 1. Last Update: Apr 1, 2016. Trail snow, not snow pack, is %115 of average.
