Rummaging around the Rumsey collection - SF 1915

I suspect this particular gem has been discussed here before, but I just wasted an hour or two rummaging around in it: SF 1915 registered to Google Maps: [rumsey.geogarage.com]
With the help of the old map, I was able to follow quite a few lines around even in today's land use. Odd sized or located parcels, diagonal walls, etc. are good clues but the old map confirmed many of them. Some moved, of course - Ocean Shore obviously relocated along Army St. (now Cesar Chavez) at some point. But a few interesting items turned up.
The Mission Bay development has something reminiscent of a roundhouse framework at exactly the location where one was in 1915: zoom in just north of 4th & Mariposa, and note the transition from the roundhouse on the old map to the partial dome-like thing in "Mariposa Park" in the underlying Google sat view - which is still in early construction in the normal Google sat view so apparently the Rumsey people got access to newer photos. [rumsey.geogarage.com]
Unfortuntately, Google's street view kind of gives up under freeways, popping you up on top, so it's hard to get a few along Iowa St. under 280. Was the SP/WP connection between 22nd & 23rd torn up before the freeway was built?
For those wondering where it will all fall down in the next big earthquake, the map does a pretty good job of showing were the creeks, ponds, and larger marshes/sloughs were at the time. Mercy H.S., Stonestown, and some large parking structures at SF State, for instance, are on filled creeks and arms of Lake Merced. The garage wasn't there in 1957 - if it had been, it might have been rubble considering how well Parkmerced's towers cracked. A piece of a "proposed sewer" seems to still exist along Junipero Serra. Turn off "45 deg" view in the underlying Google to get the best match between old and new; you might also have to zoom out and in a step or 2. [rumsey.geogarage.com]
Somebody mentioned the Dolores St. viaduct some time back. Check it out: [rumsey.geogarage.com]
Check it out. They also have older maps and other areas, again some of which have I think been mentioned here before. Happy virtual railfanning!
