Height off 3DEP inside the park’s own boundary; each band carries the date our model gives that elevation, corrections and all. The percentage is how much of the park stands in it.
That’s 6 days later than our model alone would say. This season’s reports from the ground moved it, and they outrank us.
The place
More than 300 glaciers packed into some of the most violent topography in the Lower 48. North Cascades is what the Alps would look like if nobody built ski resorts on them. Peaks go from valley floor to summit in vertical miles, not horizontal ones, and getting deep into the backcountry requires actual effort.
Established 1968. About 1 million/year visitors.

This forecast is built from the species that stand here, their elevation and this September’s weather, and corrected in season by cameras, foresters and our own crew. Out here we score it against NASA's satellite record of when the canopy shuts down, read inside each unit’s own boundary: two dates in three land within 12 days of it. How this map is made
