The morning sun hits the new foliage and makes a beautiful shape: http://gallery.leica-users.org/v/don_dory_gmail_com/Tuesday+Trees/Desert+Willow.jpg.html I found this tree seemingly doing well growing in rocks; admittedly at the edge of Barton Creek which goes dry most of the year; http://gallery.leica-users.org/v/don_dory_gmail_com/Tuesday+Trees/determined+tree.jpg.html Austin sits on a large limestone bed formed when a sea/ocean covered this geographical area. This image shows what determined trees can do with the layers that are more clay than limestone: http://gallery.leica-users.org/v/don_dory_gmail_com/Tuesday+Trees/cedar+grove+on+limestone+shelf.jpg.html Continuing that same theme, this tree is doing fine in the same conditions. What you are seeing is evidence of climate change a few million years ago. Something prevented the various shellfish from dying and falling to the bottom of the seabed for a large number of years with only fallout from the sky and runoff from the land to deposit on the seabed. http://gallery.leica-users.org/v/don_dory_gmail_com/Tuesday+Trees/advantage+found+in+the+clay.jpg.html Interesting to note the vast limestone deposits in the Kansas/Missouri border around Kansas City do not show these clay layers but are limestone for tens to hundreds of meters. All the best.
