The Paradise Ice Caves (also known as the Paradise Glacier Caves) were a system of interconnected glacier caves located within Mount Rainier's Paradise Glacier in the United States. These glacier caves were visited and documented at least as early as 1908.[1] They have a varied natural history, as their size and even existence has changed over time, from a maximum surveyed length of 13.25 kilometers in 1978, to not existing at all during both the 1940s and 1990s[2] due to glacial recession. In 1978 they were the longest mapped system of glacier caves in the world.[3] References1. ^Caving International magazine, No. 4, p 31 2. ^Caving International magazine, No. 4, p 32 - 33 3. ^{{cite web | title=Thin Ice - Exploring Mount Hood's Glacier Caves | url=http://www.opb.org/glaciercaves/ | accessdate=2013-10-07}} External links
