In 1961, Billboard magazine launched a chart ranking the top-performing songs in the United States which were considered to be "easy listening". The chart has undergone various name changes and since 1996 has been published under the title Adult Contemporary. Initially, the listing was compiled simply by extracting from the magazine's pop music chart, the Hot 100, those songs which were deemed by the magazine's staff to fit under the Easy Listening banner and ranking them according to their placings on the Hot 100. In 1961, seven different songs topped the Easy Listening chart in 24 issues of the magazine. The number one song on the first Easy Listening chart was "The Boll Weevil Song" by Brook Benton (pictured), which was at number 2 on the Hot 100 that week. The longest-running Easy Listening number one of 1961 was "Big Bad John" by Jimmy Dean, which spent the final ten weeks of the year in the top spot. It was one of three songs to top the Hot 100 as well as the Easy Listening chart during the year, along with "Wooden Heart" by Joe Dowell and "Michael" by the Highwaymen. (Full list...)

Grand Prismatic Spring

Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world. It is located in the Midway Geyser Basin. Grand Prismatic Spring was noted by geologists working in the Hayden Geological Survey of 1871, and named by them for its striking coloration. Its colors match most of those seen in the rainbow dispersion of white light by an optical prism: red, orange, yellow, green, and blue. The bright, vivid colors in the spring are the result of microbial mats around the edges of the mineral-rich water. The mats produce colors ranging from green to red; the amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids and on the temperature gradient in the runoff. In the summer, the mats tend to be orange and red, whereas in the winter the mats are usually dark green. The deep blue color of the water in the center of the pool results from the intrinsic blue color of water. The effect is strongest in the center of the spring, because of its sterility and depth.
