Sand Mountain for Sand Dune Week

Two dune posts in a row in a row creates a geoblogosphere meme, and Sand Dune Week has been proclaimed!
Sand Mountain — located on Highway 50 about 25 miles east of Fallon, NV — is a perfect candidate for Dune Week, being one of those booming or singing dunes described here on Cocktail Party Physics.

View angle, time of year and day (sun angle), and weather all affect the seemingly shifting appearance of Sand Mountain, sometimes dramatically. The first photo (above)was taken from the west-southwest during the middle of an early March day last spring, 2011.
This second photo was taken from the south in the late afternoon in late May, also 2011. Enlargement of the second photo will reveal a barely visible white line on the east side of the dune: the RV city usually sitting in the lee of the dune, where ATVers gather to run up and and down the face.
Here's the mountain in a wind storm, a late afternoon in mid-May of 2009. Any RVs present are getting sand blasted!
Lighting for pictures can be quite variable, and I often get flat pictures just driving by at random times of the day. But even mid-summer can be good for shadows and details, as shown by this photo taken early one morning in early July, 2010. Enlargement of this photo shows two tiny-looking ATVs on the west side (far left) of the dune, behind and a little to the right of a foreground dark spot that is possibly a rock or large bush. Look carefully!

Although I've driven up to the RV city and to the half buried Sand Springs Pony Express station, I've never gone on the dune to try to make it boom.

One thing that can be done fairly easily, as part of this mini virtual field trip, is to follow the sand from Sand Mountain back to its original source, back to the southwest across a mountain or two, then across Highway 95 south of Fallon, southwest toward the delta of the Walker River, where the river emptied into ancient Lake Lahontan. Start with this map and this air photo, then go here (scale change), then here, and then here (direction change). The last air photo is mostly below the high stand of Lake Lahontan, but shows the final current destination of the Walker River: Walker Lake.
