While the surrounding land seems to lack color, close inspection reveals subtle color forested areas, for example, are dark green (obscured in places by thin clouds). The image is natural color (OLI bands 4, 3, and 2), which is what your eyes would see if you looked down on the lake on that day. According to the national park, the last time the lake froze over was in 1949.Īs a result, the deep blue of the unfrozen lake contrasts with the white and gray surroundings.
At 1,943 feet (592 meters) deep, Crater Lake is the deepest lake in the United States and among the deepest in the world. That’s the case most years due to the lake’s huge volume of water and relatively small surface area. As of April 4, 2023, the snow depth reached 170 inches (more than 60 inches above average).ĭespite the snowy winter and spring, the lake’s surface remained unfrozen. On this day, the National Weather Service reported that snow at the park measured a depth of 130 inches (27 inches above the 1991–2020 average).
The Operational Land Imager (OLI) on Landsat 8 acquired this image of the lake on March 18, 2023. Yet abundant snowfall in this part of south-central Oregon prevents many people from accessing the lake and witnessing its seasonal beauty.
Today’s story is the answer to the March 2023 puzzler.Ĭrater Lake draws the most visitors throughout the summer months, but the volcanic lake is especially scenic in winter and spring when its deep-blue waters contrast with a blanket of snow.
