[Leica] Tuesday Trees

Greetings to all.  I am going to start with an abstract of a Desert Willow
growing in my backyard.  The morning sun hits the new foliage and makes a
beautiful shape:

I found this tree seemingly doing well growing in rocks; admittedly at the
edge of Barton Creek which goes dry most of the year;

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:

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.

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.
