| Backcountry Avalanche List - Wasatch and Uinta Mountains 2007-08 | ||||||||||||||||||
| 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. | Color Codes: | Region Codes: | ||||||||||||||||
