Not 30,000 found. Hundreds found and the recent lidar survey was used to estimate the possible number of earthworks.

Great idea Daniel. Cloudy and rain here on the Oregon coast, albeit the clouds parted for several minutes in front of the moon last night. Impressively out of place.
Wish I was at Newark Earthworks again this time. I was there in Oct. 2005 for lunar major.

Some local news today of global significance. The Hopewell Earthworks are added to the UNESCO World Heritage list! Some of these are in the town where I live, and they're very cool. They look like low mounds arranged in large geometric figures. There's a giant circle, and an even bigger octagon!

This article in our local paper has more details and pictures.
