San Yi Xiang Firn-basin (Lushan Botanic Garden)

This firn basin was named by Li Si Guang, a famous geologist and the originator of geo-mechanics in China . A firn basin is where glacial ice accumulates. This was the ice depository throughout four glacial eras. The rich soil and gentle slope made it a paradise for plants. Therefore in 1934 the site was chosen for a botanical garden. It was the first sub-tropic alpine botanical garden in China .
