These photos were taken either by NWAC staff or by contributors in the area indicated. All images are copyrighted and should not be used without permission of the photographers. If you wish to contribute relevant avalanche related photos, we will try to post them within a day or two of submission (earlier if possible). In order to expedite the posting process, please prepare your photos as jpeg files around 100K as a compressed file size and about 450 pixels on their longest dimension. Also, if possible please caption the photo using the "metadata" of the file or send related info in the email. By emailing photos to the NWAC, we assume that we have your permission to post them unless indicated otherwise. Please e-mail photos to nwac.sew@noaa.gov.
