Paradise & Crater Lake Snowfall/Snowdepth Plots         (page created February 2005, data last updated March 2011)


See the main Cascade Snowfall and Snowdepth page, plus Snow Season Reports: 2005-2006, 2004-2005, 2003-2004, 2002-2003

    This page displays combined snowfall and snowdepth data for Mount Rainier Paradise and Crater Lake National Park headquarters, starting with the 1916-17 season. These sites are of great importance because they are the only high-elevation, high-snowfall locations in the Cascade Range which have reasonably complete weather records covering the entire year over a period of several decades. I have written a custom plotting program (using PHP and the GD graphics library) to display the data for any season or site, with user-selectable options for which data and plot elements are shown, including average, maximum, and minimum values. The ENSO status can be displayed for seasons since 1949-50. See the Notes and Version History below for additional info.
    The plotting program is new as of February 2005, updated April 2005. Please notify me of any problems or bugs, and I will attempt to fix them as soon as possible.

The seasonal snowfall total covers
the July 1 - June 30 period, not the
Sept 1 - August 31 period shown
on the graph. If marked with * the
total is approximate, some days or
months of data may be missing.
Monthly snowfall values marked
with * are also approximate.
Record high or low values are
colored green or red.
Useful Information and Notes

•  There are a few completely missing (or nearly so) seasons of data within each site's period of record: 1918-19 and 1949-50 for Mount Rainier Paradise, and 1925-26, 1928-29, and 1942-46 for Crater Lake. Both sites have various other missing values, especially several decades ago, but overall they each have about 95% of possible data values within their period of record.        
Examples of really huge snow seasons: 1916-17, 1926-27, 1932-33, 1949-50, 1955-56, 1970-71, 1971-72, 1973-74, 1982-83, 1996-97, 1998-99, 2007-2008
Examples of very poor snow seasons: 1929-30, 1933-34, 1940-41, 1941-42, 1962-63, 1976-77, 1980-81, 1991-92, 2000-2001, 2004-2005
Some weird or unusual snow seasons:  1930-31, 1944-45, 1975-76, 1989-90, 2002-2003
