14-er
 n.— «As a man in his 70s, Dr. Reed started climbing the “14-ers,” as they are called: the dozens of mountains in Colorado that rise to 14,000 feet or higher. Friends said that on those steep mountains, where the air grows thin, he outclimbed friends two to three decades younger.» —“Dr. Cramer Reed dies at 91″ by Roy Wenzl Wichita Eagle (Kansas) Apr. 12, 2007.
