archaeological BMX find.

While riding around I stumbled on these dirt/jumps. Grown over with junipers and yucca Cactus between them. Guessing 30-40 years ago.

 

Don't tell @DangerDirtyD - he'll have them proclaimed a historical monument.

 

Just waiting for some love!

 

Look at them on Google Earth and then find them on www.historicaerials.com (click on the "viewer") to see if you can tell when they were built. They need to be at least 50 years old and portray some sort of unique engineering or workmanship; or consist of unique materials; or be associated with someone important in history; or characterize a period of time important to the history of the local area, State, or country; or (and this is the best one) have the potential to provide additional information that would shape the history of the activity or location whereat the activity occurred....or something like that...I think..?

 

Amazing they are still around without the area being developed.

 

Yesterday I found out in the early sixties there was a race track right in Acton. Photos and description were right at this spot. Couldn't find it again this morning & off to work. Guessing the kids on stingrays were much more gifted than I remember.

 

If this was in the OC, it would be in someone's backyard now.
