Note: If you simply click on the links below, the images
will be displayed in your browser in greatly enlarged fashion. To
save the images at their nominal scales, click on the link, hold the
mouse button down (right button on a PC), and choose "Save this link
as..." in Netscape or "Save target as.." in MS Explorer. Then use
Photoshop, ArcView, or some similar image viewer to see the files at
their proper scales.
Some of the files have names longer than eight characters. If you
are running Windows 95 or earlier, you will need to download these
using the "save as" procedure above and rename the file to something
8 characters or shorter, not including the three-letter extension

- Lone Tree Creek Airphotos
-
- These photos were scanned at 600 pixels per inch (ppi) into
Adobe Photoshop 5.5 and saved as medium quality jpeg files. The
USGS photos are 2X enlargements of just the Lone Tree Creek
region. They have a nominal scale of 1:12000. The Bay Area Transit
Survey (BATS) photos have a scale of 1:12000. The 1973 photos are
from a special flight flown by the USGS at Luna Leopold's request.
The prints became somewhat moisture-damaged in storage.

Lone Tree Creek DEMs
-
- The Lone Tree Creek are lies in the SW quadrant of the San

- Chittenden, CA (Lomerias Muertas)
Airphotos
-
- These photos of the Lomerias Muertas in the SE quadrant of the
Chittenden 7.5' quadrangle were scanned at 600 pixels per inch
(ppi) into Adobe Photoshop 5.5 and saved as high quality jpeg
files. Because the flight lines run E-W instead of the
conventional N-S, the photos have been rotated so that the headers
lie along their left margin.
