This is a photo of Grinell Lake in Glacier NP. One of the first things that I noticed about the lake was the striking color. It looks unnaturally green. I came to find out that the color is typical of lakes fed by glacier run off. Rock flour, or glacial flour, consists of fine particles of rock, generated by mechanical grinding of bedrock by glacial erosion. Because the material is very small, it can become suspended, making the water appear cloudy, also known as glacial milk. (Thank you Wikipedia)
To me, this is a wonderful reminder of some of the ways that God works in our lives. Similar to being “gold tested by fire,” being rock ground by a glacier is sometimes a painful experience. But the result is a work of beauty.
