For the first time since the 1950s, Denali's Muldrow Glacier is surging! It is estimated that the glacier is currently advancing between 10-20 meters (30-60 ft) a day. This has major implications for the popular north side climbing route, and may lead to a significant flood of the McKinley River. The surge may have started as early as January of this year and could continue for several more months.
The River Forecast Center released their spring breakup forecast for 2020. Flood potential is expected to be above average for areas south of the Brooks Range. Areas of north of the Brooks Range should see a normal flood potential.
