There are some serious red soils on the eastern seaboard as well. Parts
of Virginia and South Carolina have some of the reddest soil you will
ever find. (Interestingly, very near the Chesapeake Bay impact
structure, ~100 km wide and of age 35Ma), and for the master of the red
dirt, you have Prince Edward Island, in the Canadian Maritimes. The soil
there is so red , that it can permanently stained your clothes if you
sit in it. They even sell tee shirts that have been soaked in the stuff,
and are permanently dyed. Much of Underlying Nova Scotia has this red
soil as well, and interesting again is that it borders the off shore
impact crater Montagnais, a 45 km wide structure aged about 50ma Almost
as close is the impact structure Charlevoix, a 54 km wide crater of age
~350Ma. I don't know if any of this iron-rich soil and sandstone has
anything to do with the impact structures, but they are topographic
cousins in any case.

If you want to speculate on "rusting impactors" you may not have to go
quite
so far. Come on over to East Texas (and many points in the southeast
US) --
Everything -- from the clay to the rock is red and much of it (the rock)
is
magnetic. In fact the main road bed material in use out here is called
"iron ore gravel". They dig this stuff up and process out gravel that
is as
red, orange and black as mars looks on any pictures I've seen. Much of
the
farmland around here has a deep layer of white/beige sand, but
underneath at
some point is red clay/rock sedimentary formation. We have the Marquez
impactor site just south of us?????
Also in central Texas in and around Bastrop (east of Austin) is a
roughly
circular area several miles across know as the Lost Pines. It is an
area of
pine trees, red acid soil/clay that is surrounded by post oak savannah,
alkaline soil/limestone. Never have heard what caused this area to be
where
it is??? Very old impactor site??? Who knows -- maybe some of those
teasips at tu in Austin. (from an Aggie Dad)
