#10 reminds me of the hills climbing from Albuquerque to Santa Fe. Sand hills? Nice, not that your summer scenes aren't all food for the winter soul.....- Desert Dweller/David C.
AH I should have looked at the photo! This is a former scoria 'pit'or quarry! Scoria and a sandstone/limestone (the old sea bed that the volcanic activity threw up) everything in here is growing without any topsoil! The main tree is self sown Pinus radiata from California and a lot of echiums from the Canary islands! The herbaceous stuff is mostly native stuff that does not exist outside of here much because the pasture grasses are much to dominant for these to survive! It is also sanctuary for a small band of Black wallabies!
Ahhh I only know those places from Neil Young songs!! NO I live on a volcanic plain..some of the very youngest soils in Australia! The 'hills'; were the LAST eruption points and they largely consist of Scoria. http://vro.dpi.vic.gov.au/dpi/vro/glenregn.nsf/pages/eruption_points_noorat
