San Juan Snow Conditions - January 2022

After a rough start, the snow pack in the San Juan Mountains is in good shape at the start of 2022!

Snowfall and the snowpack in the San Juan Mountains have been highly erratic in the closing months of 2021. The four plots to the side summarize the monthly snow conditions in the San Juan Mountains as measured at the Red Mountain Pass SNOTEL site.

The snowfall (first plot) in October was nearly double the monthly average, followed by a very dry November. The snowfall rebounded in December with 54 inches (124% of normal). The snowpack (second plot) was normal on the first day of November, but significant melting during the month resulted in a snowpack on the first of December that only about half of normal. Significant snowfall in December (more than 50 inches) has resulted in an above-average snowpack on the first of January (54 inches). For comparison, the largest snowpack on January 1st was 62 inches (in 2008 and 1996).

The Snow-Water Equivalent (SWE) (third plot) is the amount of water that will be released from the snowpack when it melts. A SWE at the Red Mountain Pass site of 23” (orange dashed line in the figure) on June 1st is the threshold used by the run management to evaluate if the event can be safely held. Snow can melt fast in the spring – while the average SWE on May 1st is 22 inches, it falls to an average of 8 ½ inches by June 1st. For comparison, the SWE was 33.6 inches on June 1st 2019, which lead to the eventual cancelation of the run that year. The current SWE at Red Mountain Pass is 11.8 inches which is above the average amount of 10 inches.

How does the monthly snowfall at the Red Mountain Pass SNOTEL Site compare to Silverton (which Charlie Thorn compiles and is listed below)? The fourth plot shows that the monthly snowfall for the two locations is quite similar (particularly for the months of February and March); early and late in the season the average difference in snowfall can be as much as five inches. It is interesting to note the Silverton has significantly more snowfall variation (much high standard deviation about the mean than Red Mountain Pass).

Money is donated by runners, volunteers and friends of the Hardrock Hundred Endurance Run, a 100-mile footrace which starts and ends in Silverton each July.
