Page History:
January 2010Original version with 18 camera views, designed based on the Mount Rainier Paradise WebCams webpage, with cameras from the Washington Mountain WebCams webpage
Includes the option to show the last 24 hours of NWAC and SNOTEL telemetry data from near Snoqualmie Pass below the webcams
Includes code to error-check for missing SNOTEL data
February 2010 Added new cameras at top of Alpental and Wildside lift at Summit West, temporarily removed two of the WSDOT cams which have a long-term outage
March 2010Fixed broken links to SNOTEL website
May 2010Fixed unwanted line breaks in SNOTEL telemetry dates on narrow screens
November 2010 Expanded to 19 camera views, re-activating the Franklin Falls cam which had been offline for most of 2010
Fixed a minor bug in the SNOTEL data display, which only occurred between 11pm and midnight and showed the previous day's date for the 0000 hour's data row
December 2010Added an Alpental webcam and removed the long-defunct Hyak East webcam, keeping the total at 19 camera views
March 2011 Fixed a minor quirk in the SNOTEL data display, which only occurred when SNOTEL data is not available at a given site for the previous 24 hours
February 2012Updated the URLs from which to download the SNOTEL data, which had recently been changed slightly
April 2012Updated several WSDOT camera URLs, which had recently been changed
October 2012Added name and milepost info for several WSDOT camera views which had been missing them
November 2012Expanded to 21 camera views, adding 2 WSDOT camera farther east of the pass
Revised the page layout to use separate tables for each row, to better accommodate the very different widths of images
December 2012Added more code to properly handle the new HTTP Status 404 errors from the SNOTEL server, and other unknown SNOTEL errors
January 2013Expanded to 26 camera views and rearranged images into 4 rows, adding 3 more WSDOT cams, 2 views of Mount Si, and KING-TV Snoqualmie Pass cam, removing the Summit West KIRO-TV cam (which had switched to an annoying variable URL since September 2011)
March 2013 Forced to write a new external script to grab SNOTEL data, after the long-existing SNOTEL data programs on the NWCC website were suddenly redirected to a beta-version report generator
The new script is a major improvement, it displays wind and solar data for any SNOTEL sites which have those sensors, mostly installed within the last few years
Added the nearby Mount Gardner SNOTEL site
September 2013Fixed one camera link which had changed
November 2013Expanded to 27 camera views, reinstating the Summit West KIRO-TV cam with code to detect its annoying variable URL
December 2013 Expanded to 29 camera views, adding the WSDOT West Nelson and KCDOT Meadowbrook Bridge in Snoqualmie cams
Added the 4 other SNOTEL sites near Snoqualmie Pass (Cougar Mountain, Rex River, Meadows Pass, Sawmill Ridge), along with the Mt Washington NWAC site (which is not linked from the NWAC website, available in the text data folder only)
July 2014Expanded to 36 camera views and rearranged images into 5 rows, adding the new Silver Fir cam and the new WSDOT North Bend, Tinkham Road, Asahel Curtis, Rockdale, East Snoqualmie Summit, and Old Keechelus Snow Shed cams
September 2014Expanded to 42 camera views and rearranged images into 6 rows, adding the WSDOT Sunset Way, East Easton, Bullfrog East, Indian John Hill, Rocky Canyon, and Thorp cams, plus fixed one camera link which had changed
November 2014Expanded to 43 camera views, adding the KIRO-TV Snoqualmie Casino Cam, fixed two camera links which had changed, updated several URLs
December 2014 Expanded to 45 camera views, adding the WSDOT Ellensburg and Manastash Ridge cams
Added the Lynn Lake SNOTEL site, since it was the only nearby site not yet included on this page, plus improved the location info for several SNOTEL sites
April 2015 Expanded to 46 camera views, adding the Suncadia Lodge cam
