Snow Depth Measurements: 2007 – 2020

Keith Cox measuring snow depth at The Summit station #2.

Have a look at the data and graphs below. What patterns appear to be emerging? 

Will accelerating climate change affect the snow pack on our Larch Hills Ski Area?

Each Winter Season’s Snowfall Accumulation is different. We know this based on our snow shovelling efforts around home. Compare the snowfall accumulation/depletion patterns in the graphs below for the period early January thru late March /early April for past 6 seasons (2015 – 2020) at the same 4 elevations: 1000 M, 1057 M, 1200 M and 1400 M along the Larch Hills Trails

Snow depth measurements for late March / early April will be added to this graph in early April 2020
Winter 2018: With frequent snowfalls and cooler average temperatures early March 2018 snow depths were about 40% above the 12-year average for S. Hub (1057m), Cec’s (1200m) and the Summit (1400m).  
At the Chalet (1000m) early March snow depths of 106 cm were about 75% above the 12-year average early March snow depth of 61 cm.

“Snow Rangers”, Jim & Marcia and Keith skied, hiked and “water skied” to the Summit on April 2, 2015 to measure snow depths. A sunny 5 hour expedition!

Observations and 12-Yr. Averages from 2007 to 2018

  • The minimum early March snow depth measured at the Chalet was in 2010: 4 cm
  • The maximum early March snow depth measured at the Chalet was in 2018: 106 cm.
  • 12-year average early March snow depth measured at the Chalet (1000M elevation) is 62 cm.

Reports

2017- 2018 Snow Depth Observations and Wrap-Up

  • Between 1000M (Chalet) and 1400M (The Summit) based on 2007 – 2018 early March Total snow depth measurements it appears snow depths increase by 2.1 times – more than double (62 cm to 131 cm).
  • Between 1000M (Chalet) and 1200M (Cec’s Cabin) based on 2007 – 2018 early March Total snow depth measurements it appears snow depths increase by 1.8 times –  less than double (62 cm to 112 cm).
  • Between 1000M (Chalet) and 1057M (South Hub) based on 2007 – 2017 early March 10 Year Total snow depth measurements it appears snow depths increase by 1.5 times (62 cm to 93 cm).
  • Next Report in early March 2019 – the 13th consecutive year of these Larch Hills paired, 4 elevations, snow depth measurements.
  • Next snow depth measurements in early January 2019.
