University Heights – 1888

San Diego has changed quite a bit since it was first laid out in the late 1700’s. As the city grew, new neighborhoods were planned farther out from the city center. One of these, University Heights, is still around today by the same name albeit covering a smaller area. The original plan, from 1888, was mostly built and is still quite recognizable today. One major item, a lake known as Mystic Lake, was never constructed. Today, the canyon remains undeveloped and is considered public open space. In addition to the lake,

The map also shows a small section of right-of-way for a railroad just east of Park Blvd. This railroad, the University Heights Motor Road, was built as a way to bring prospective buyers from downtown to East San Diego (later City Heights). It was dismantled not long after construction but traces still remain on maps and in Switzer Canyon.

The name, University Heights, stems from a planned university that was to be sited there. A small teacher’s college, which later became San Diego State University, was indeed located there. In the 1950’s, the structures were mostly torn down except one which remains today. The site is the headquarters for the San Diego Unified School District.

San Diego Fossils

I’ve been doing a bit of work lately on my geologic study of central San Diego and have found many fossil sites. So far, none of the fossils have been very complete. Mostly shell fragments in condensed layers. The oldest found so far have been from the Eocene Mission Valley Formation, which is between 40 and 48 mya.

In addition to the fossils found in Presidio Park, I have also found a few locations around Hillcrest and South Park. Some of these are just the side of the road, others you have to hike a bit in a canyon.

Underlying the southern half of the central San Diego Mesa is the San Diego Formation, which is late Pliocene to early Pleistocene in age, about 5 to 1.5 mya. It has many layers containing fossils, such as the one pictured above.

Once you get the “eye” for fossils, they seem like they pop up everywhere. It would seem that every time I go out on my mapping project lately, I find fossils. Geology can be a lot of fun and I encourage all interested to go out and explore their local area. You never know what you might find.

San Diego Electric Railway Exposed!

For the first time since 1949, a section of the San Diego Electric Railway, double track at that, is exposed for only a short time before it will be destroyed in Hillcrest. They last saw service on April 23, 1949 as a part of the #7 streetcar line. The City of San Diego is currently restoring the 1914 Georgia St bridge over University Ave. As a part of this project, they are also lowering University Ave between Park Blvd and Florida St.

These tracks represent a bit of San Diego history and I highly recommend a visit in the next week or so before they are gone. Remnants of the former railway are getting harder to find as time passes and more roads are torn up for various projects.

Looking east from Georgia St, tracks are in the median.
