La Jolla Underwater Rocks and Structure
 

Do these locations have common names?

Probably won't go out far enough to reach most of these locations, but I was just curious if there's any information on any of them, especially #3 which is just bizarre.

It looks too straight to be natural but what would have created it? I suppose it's possibly just a data error, there's plenty of artefacts in this data set so it could just be a glitch, but looks too precise compared to other instances on the map.

If anyone has a more accurate data set I can use instead that would be appreciated, since this set has pretty bad noise for the south ridge of the canyon, north west of the point. This data is from: http://www.ngdc.noaa.gov/dem/squareC.../download/3543

I use google earth for all the areas I fish. You can drop a pin down and it will give you the exact numbers for the spot. Get a good amount of number and just plug into your electronics. Delete the ones that are no good. Also google earth is pretty high def as well
