Dan McGrath Members of the CSU team, Ella Bump (left) and Lucas Zeller (right), work at one of their research sites on Cameron Pass. As Colorado enters the hottest months of the year, drought and high temperatures are on most people's minds. But researchers at Colorado State University are still focused on snow. For the past few winters, CSU professor Dan McGrath and his graduate students have made a bi-weekly trek up Cameron Pass. When they arrive, they split into various tasks designed to measure the snowpack. Some of the team will strap on snowshoes and start pulling a large sled. The sled holds a ground-penetrating radar system.
