Something to remember during my upcoming hiking trip to Seattle: it appears that the glaciers around Mt. Rainier are acting up. Apparently, during hot weather, water melts within and underneath glaciers, and after it reaches a critical pressure, it breaks free in what’s called a glacial outburst. Seeing that Noah and I are planning (at least as of the last time I asked) to hike the Blue Glacier, maybe we should be a little careful.
