Mountain Powder is a homegrown tool built to standardize weather, snow, lift, trail and activity tracking hardware/software across the resorts in Alterra’s portfolio. Mtn Powder’s aim is to consolidate those different sources into one clean data set, as well as provide easy-to-use tools to self report on lifts, trails, and snowfall data. In addition, Mtn Powder has many other bolt-on features such as historical weather auditing and text message alerting.

Feed Sources

Currently Mountain Powder fetches data from the following data sources:
Open Snow - Weather and Snow Forecasts, they get source data from NOAA and other models and hand edit each resort to match expected conditions daily. Widely regarded as the best in the business.
Aeris Weather - Current conditions from on-mountain weather stations. These are a mix of consumer grade devices and true METAR stations owned and operated by NOAA.
SnoCountry - Ikon Pass partner resorts snowfall, lift, and trail information. We are sunsetting the use of this in alignment with projects in progress.
1Risk - Lift & trail statuses
SkyLynx - Lift wait times (feature turned on for Palisades Tahoe Only)
NOAA - Narrative forecast information
CALTrans - California traffic Information
Big Bear Traffic - Big Bear area traffic Information
