Season Vertical Detail for Mammoth and Totals

The first three rows of the table below show the vertical skied by season for Mammoth Mt., June Mt., Tioga Pass and China Peak, the 8th, 13th, 104th and 241st areas I have skied. The remaining rows are totals for all areas skied within each ski season.

Below the table are links to online reports from this region. Reports up to February 2003 were from the Southland Ski Server. Later reports, usually including pictures, are from First Tracks Online Ski Magazine No-Bull Ski Reports.

Mammoth is the closest I have to a "home" ski area, representing about 30% of my skiing, starting in 1978. I'm first listing here a few reports from China Peak, June Mt. and backcountry on Tioga Pass. Then Mammoth reports are grouped by time of season.

Mammoth, Early Season
Pre-Christmas skiing is generally worthwhile only on relatively short notice at ski areas within driving distance from home. Sierra snowfall is notoriously volatile, so in the dry years not worthwhile until well past the holidays. But the volatility works both ways. The better early seasons have substantial dumps, opening expansive and steep terrain and not confining skiers to a handful of groomed runs on manmade snow. November storms on the West Coast are prone to a high rain/snow line, but Mammoth will generally get all snow at its 8,900 foot Main Lodge and above.

Mammoth, WWSRA Demo
In 2011 I was coincidentally at Mammoth at the time of the Western Winter Sports Reps Association annual ski demo. This media and trade event is held each year shortly after the Snowsports Industry America trade show in Denver. The demo occupies the entire Chair 2 parking lot at Mammoth, an ideal location to test skis over a wide variety of terrain, so I have returned to this event when weather and my schedule have permitted.

Mammoth, Early Spring
This is Mammoth's prime time, especially relative to other ski areas. Only in 1977 and 2015 was Mammoth not fully covered by April. All lifts and terrain are open to the third weekend of April. High altitude and predominant north exposure mean that the upper steeps usually retain winter snow well into April. When the warm weather does arrive, there is often ideal spring corn. April is my most skied month at Mammoth.

Mammoth, Late Spring
Mammoth is a premier area of North America in late season. It remained open to Memorial Day during all of the severe 2012-2015 drought years. During most seasons Mammoth is close to half open to Memorial Day, including steep upper runs that close in spring at ski areas with less stable snowpacks. Salting of groomed runs makes Mammoth's late season more pleasant for intermediates too.

Mammoth, Summer
Mammoth has been open to July 4 in its best 30% of seasons of the past 40 years. Some of the steeps remain open to closing day, along with a few salted groomers. Lift hours are typically 7:30AM - 1PM. Lift service continued past July 4 in 1983, 1995, 2017 and 2019.
