CORONA satellite photograph over the Lucheng site taken on September 29, 1969.

You can find the oval enclosure of Lucheng city ruins on the satellite photograph. According to Prof. Wei's explanation, remains of the city wall date back to the Han period or even earlier. We saw many tombs and debris of artifacts in the surrounding area. The most prominent feature observable in the satellite photograph and on the ground is the network of irrigation canals, indicating that agriculture based on the irrigation system once carried on. However, because of the subsquent change in the environment, this area is mostly uninhabitable desert today.
