A glacier burst, flooding Juneau. Again. This one broke records
Flooding from meltwater is getting worse in Alaska’s capital. Here’s what’s causing it
A few decades ago, a tributary glacier fed into Mendenhall Glacier (visible at the valley bottom). Warming caused it to retreat, leaving behind a barren rock bowl that fills with rain and meltwater each summer. That water escapes beneath the glacier, unleashing a flood of up to 60 million cubic meters toward Juneau, Alaska.
