Terraserver aerial images for trip planning?
Posted: Thu Dec 29, 2005 4:15 pm
Any of you others use those aerial images for trip planning? Well if not maybe the following will add a new resource for a few of you.
The last month given the onslaught of winter, have been wiling away a fair amount of time trip planning. I have a huge pile of mutilated 7.5 minute topos that I'll puruse for ideas. Also have a few of the topozone CD's. When I'm looking at areas I've never been to, I often also like to bring up terraserver in order to look at aerial images. Near timberline looking areas with scattered trees are always more appealing than the highest bare rocky canyons with patches of turf and barren icy waters. So I'll bring up terraserver and go into topo mode in order to zero in on some location. Then when sufficiently zoomed in switch to aerial mode to see what it looks like. Trees show up as little black specs. Lakes are dark, and meadows or turfy areas somewhat dim while granite is always lightest. Metamorphic rock areas definitely look different than granite. There is much to glean from these crude views. For prospective campspots in such areas, I always look for where clumps of trees are, and then mark them on my topo. More often than not those spots are exactly where we end up camping since in alpine zones mid summer the high midday sun is to be avoided hiding in some shady camp spot looking out at the scenery.
Hikerduane just put up a thread about an area I haven't visited, The Pinnacles basins off of Piute Creek. The first link below is zoomed out some and shows big Three Island Lake in the upper left quadrant. The second link shows some of the lakes in the East Pinnacles basin. One of the lakes is shaped like South America. There are certainly a few scattered trees there too, certain to be whitebark pines. In order to re-discover one's point of reference, terraserver has both an aerial and topo tab which one can toggle between that maintain exact positioning. One thing I always am fascinated by looking at these Sierra aerials is how strongly granite joint cracks crisscross landscapes. Far more apparent than when hiking about. One notices how trees tend to fill such little crack ravines as that is where more organic debris and soil has accumulated. ...David

This next link is to well scenically admired Pioneer Basin that for some reason I've never managed to visit though have had plans to through the years. So I recently documented a trip into that which starts down at the Edison ferry dock and goes up Mono Creek. After a layover day in Pioneer Basin, my trip goes back down canyon to Second Recess and I climb up to the Lower Mills Creek area that I've been to three times in the past. But for this Pioneer Basin, I wanted to figure out where to camp at? First I had marked up my paper topos with little red arrows for all the prospective spots I might drag my 4x5 to for photos with notes on the time of day to do such. That gave me a good idea about where to centralize a campspot in order to be able to reach the various shooting locations more easily. And I am always looking for a place that offers a good view if possible instead of some place down in a blocking hole or ravine. So here is the exact spot I selected. In topo zone a red cross appears at the center of the map display and is a way I like to indicate exact map locations to others over the internet:

So it is right next to one of the smaller ponds rather than the lakes most people are more likely to camp at. The pond is atop a bench with unblocked views to the south. It is the views south towards the Abbot - Gabb peaks I expect to be most interesting. And since those peaks are distant due south, the pink nightwedge that rotates around from east-southeast towards the south at dusk might make a nice shot reflecting in the pond. In any case we always consider any spot I figured out like this as a mere prospect and then when actually there, scour the area carefully for the finest camping. Now this aerial image shows the little pond has trees next to it where I expect some other soul has already smoothed out a nice spot there beneath some stunted canopy of branches to commune with the chipmunks. ...David
