This is a list of backcountry avalanches either observed or reported to the Forest Service Utah Avalanche Center.  It is certainly not an inclusive list.  This information comes from a variety of sources.  Thus we cannot vouch for the accuracy of these reports.  We update this list usually by mid morning. For a daily 6:00 am report of yesterday's avalanche activity, call 888-999-4019x8. To report avalanche activity please leave us a message at 1-800-662-4140 or 801-524-5304.  Or send emails to staff@utahavalanchecenter.org.  Fax 801-524-6301.  We keep all identities confidential.  Many locations names come from standard USGS 7.5 minute topographic maps.  www.topozone.com is a great resource.
