Anybody know the time span between this CalTopo ( Gmap4 ) map & this Google Earth Image
Interesting that CalTopo maps a portion of the exposed / open water of Milk Lake.
Is this typical?
Other examples?
Also, I'd love to see some recent images of this lake
Thanks

Ha! I was just looking at that. Unlike "Milk" it's a unnamed lake. I suppose it'll be named "Colonial Lake"
Thanks Jeff

That's the google maps terrain layer. It does weird things like that around water and rivers.
It shows the Mid Fork as a a long narrow lake upstream of the Dingford trailhead for example.
Its just a mapping quirk. It has nothing to do with glacier melt and global warming if that's what you're getting at.

Very cool, Tom. I've looked at that lake on Google Earth and wanted to visit it sometime.

Or it’s a copy of the USGS map that shows the Milk Lake Glacier from yesteryear. So maybe it does have to do with glacier melt…or maybe that’s just a “mapping quirk” also…

Thanks Tim. Wow. 8 years ago
ETA "Tom". Not Tim. Spell check likes Tim more than Tom. Alphabetical order I suppose

Go on Google E and page through the pics at different dates. That will give you an idea of what's going on.

yeah, the areas around glacier peak seem to have these kind of mapping oddities. like when you look over at indian head peak or black mountain and you're like, hmm. unlikely to be permanent snowfields. maybe things did seem permanent when the maps were made.

Check out John Scurlock's pics link from this earlier thread.
There's a pic of Colonial Lk from a decade ago that shows much less open water than my recent pic. There are dozens of lakes emerging from under the ice. Check out the White River Glacier lakes, or Borealis lake (N of Tricouni Pk).
Back in the mid '80s I spoke with a couple USGS field monitors at South Cascade Lk. Per their info, the terminus of S Cascade Glacier was at the outlet of the lake around 1910. By the mid 1960s the glacier had receded to a point exposing the entire lake. At the time of our conversation in the '80s the terminus was well up the hill above the lake and they said the glacier was receding 15 meters per year - which would amount to a quarter mile more between the '80s and now.
Most of the USGS quads are based of the 7.5' maps charted in the 60s, so yes, a few things have changed.

The Google Maps terrain data is likely derived from the USGS Topos, so considering that the most recent revision of the Lime Mountain quadrangle (1999) still shows the glacier and just the sliver of the lake, that's almost certainly why it appears as such on Google Maps.
