More snowflakes mean more water, Kanzer said.<\/p>\n<p>Technology can help find those snowflakes, Deems said. He runs a company called Airborne Snow Observatory that uses Light Detection and Ranging \u2014 LIDAR \u2014 to measure snow across the entire landscape. Pulses of scanning laser light are shot from a plane toward the earth and reflect off the snow. With that data, they build a three-dimensional picture of the snowscape, detailed enough to show deep pockets of snow below bare slopes where avalanches occurred, or even areas where snowmaking was used to make terrain parks on a ski run.<\/p>\n<p><a href=\"https:\/\/www.skyhinews.com\/news\/smaller-snowpack-may-be-the-new-normal\/\" target=\"_blank\" rel=\"noopener noreferrer\">via:: Sky-Hi News<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Colorado River District\u2019s Deputy Chief Engineer Dave Kanzer and National Snow and Ice Data Center researcher Jeff Deems have been studying water and snowpack, and what can be done to understand them better.Courtesy Colorado River District The good news: Colorado\u2019s snowpack is normal.
