Please also note that the shipping rates for many items we sell are weight-based. ![]() Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page. When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Note that there are restrictions on some products, and some products cannot be shipped to international destinations. We can ship to virtually any address in the world. We'll notify you via e-mail of your refund once we've received and processed the returned item. If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days). You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.). Geological Surveyĭidn't find what you're looking for?

The names of the DEM tiles are eleven characters long (e.g., dem_xxxxxx) with the prefix, "dem", indicating the file is a DEM and the last seven characters corresponding to the map reference code of the quadrangle defining the tile's spatial extent. Each tile’s bounding rectangle is identical to the extent of the USGS 7.5 minute topographic quadrangles covering the same area. This release is comprised of a DEM dataset accompanied by a hillshade raster, each divided into eighteen tiles. The bathymetry is mosaicked into the DEM in place of the lidar derived lake surfaces. The bathymetric surveys were performed in June, 2001 by Bob Reynolds of Central Oregon Community College, Bend, Oregon. The lidar-derived DEM is amended to include bathymetric surveys of East Lake and Paulina Lake. Watershed Sciences was contracted to collect 500 square miles of high-precision airborne lidar data to produce a digital map of the ground surface beneath forest cover. Data were collected through the Oregon LiDAR Consortium, administered by the Oregon Department of Geology and Mineral Industries (DOGAMI). This DEM (digital elevation model) of Newberry Volcano contributes to natural hazard monitoring efforts, the study of regional geology, volcanic landforms, and landscape modification during and after future volcanic eruptions, both at Newberry Volcano or elsewhere globally.Īcquisition of these high-precision, airborne lidar (Light Detection And Ranging) data was funded as part of the American Recovery and Reinvestment Act (ARRA) of 2009. Such a long eruptive history together with recent activity suggests that Newberry Volcano is likely to erupt in the future. Newberry Volcano has erupted as recently as 1,300 years ago, but isotopic ages indicate that the volcano began its growth as early as 0.6 million years ago. It is the product of deposits from hundreds of eruptions, including at least 25 in (approximately) the last 12,000 years (the Holocene Epoch). Newberry Volcano, one of the largest Quaternary volcanoes in the conterminous United States, is a broad shield-shaped volcano measuring at least 60 km north-south by 30 km east-west with a maximum elevation of more than 2 km above sea level.
