About this postcard

The picture shows Cleopatra Terrace, one of the travertine hot-spring terraces at Mammoth Hot Springs in Yellowstone National Park, with pale, mineral-crusted steps and pools of blue-green water backed by a dense stand of evergreen trees. Steam rises from the active spring at the left, and the terraces are tinted in the pinks, oranges and yellows produced by heat-loving bacteria and algae. Mammoth Hot Springs sits atop a limestone deposit and its terraces are constantly rebuilt as hot water rich in calcium carbonate flows over them; Cleopatra Terrace is among the formations on the Mammoth Terraces. The linen-era coloring and the printed number 2A-H709 point to a mid-20th-century issue.

956 CLEOPATRA TERRACE, YELLOWSTONE NATIONAL PARK --- CLEOPATRA TERRACE Cleopatra Terrace is reached by the Terrace Trail at Mammoth Hot Springs and is one of the most prominent in that district. The deposits from these springs which build up the terraces are almost exclusively of lime and form a marble-like rock called Travertine. It deposits very rapidly as objects exposed to the waters will show a good coating in just a day or two. C. T. ART-COLORTONE, SANBORN SOUVENIR CO., DENVER, COLO. POST CARD PLACE STAMP HERE
