East Dulwich in geological time (map)

[Chener Books]

This is a reconstruction.

I have put the map (1.7mb) here.

Blocking the "Herne Hill Gap" to restore the Dulwich Hill crest before the headward erosion by the River Effra and removing the consequent slight Effra/Peck watershed that crosses East Dulwich Grove makes the geomorphology of our valley much clearer. It is partly a captured valley. The River Peck tributaries drained what is now Dulwich Village and Herne Hill.

The orientation has been changed to minimise the misdirection caused by overfamilarisation with the standard Ordnance Survey projection with north at the top.

For context the 2011 course of the River Thames is shown.

The map illustrates the original Kent/Surrey boundary quite well.

Great map. Funnily enough, when I point to where I live from my Vauxhall office I always describe it as the valley below Dawson Heights. You get a brilliant view of the geography from my office window and can clearly see the surrounding hills.

This is great - is it possible / practical to put a street map overlay to pinpoint streets & houses?

[Drxyster]

I agree with "Marmora Man", if this were possible it would be extremely interesting.

With all the human clutter around us it's easy to forget we live in a valley.

Can you take a photograph from your office window?

As you work at Vauxhall you might like to see Martin Knight's excellent work in reconstructing the River Effra basin. The Effra flows into the Thames near your office. His web-site is here.

It would be relatively easy to add streets and street names, but for such a large area a rough calculation shows that the jpg file would be c900mb [sic]. This is too large for internet/email use. I'll have to make some arrangements for anyone interested to have a copy on a DVDR.

Meanwhile there is the highly compressed jpg file here here for a smaller area on which you can trace Crimea and other East Dulwich street names.

Postscript

I find it amusing that the Choumert Road area was once East Dulwich-on-Thames.
