Idaho Snow Depth

1:1,400,000

24 inch by 20 inch flat wall map, printed on heavy fine paper. Shipped rolled.

A representation of the average snow depth in mid-March for the 19 seasons from 2004 - 2022, often the deepest moment of the year for the snowpack. This map features prominent passes for touring and all currently operating alpine ski resorts in the state of Idaho. Detailed reference labels includes places, state parks, special land management categories, alpine ski areas, special sites, highways/major roads, prominent and recognized summits and landforms of significance, and familiar hot springs (i.e. not all your secret hot springs, just the common ones ;-) ).

6th Edition print — first in the 24 inch x 20 inch sizing.

5th Edition (November 2019): Incorporated depth data from 2018 and 2019

4th Edition Update (January 2018): Incorporated depth data from 2015, 2016, and 2017.

MORE ABOUT THIS MAP

This map presents the average value of snow depth modeled for March 15th from the 19 year period of 2004 thru 2022. The mean was calculated by <em>Mitchell Geography </em>from data produced by the NOAA National Weather Service's National Operational Hydrologic Remote Sensing Center (NOHRSC) SNOw Data Assimilation System (SNODAS). SNODAS is a modelling and data assimilation system developed by the NOHRSC to provide the best possible estimates of snow cover and associated variables to support hydrologic modelling and analysis. NOHRSC products are gridded data sets for the continential United States at 1-km spatial resolution and 24-hour temporal resolution.</p><p class="">SNODAS models are run each day, with analysts deciding whether or not to use remote sensing and ground based observations (e.g. SNOTEL) to update the snow water equivalent state in the model.
