In afternoon of August It,,1981, Dryden and'I 
visited ♦•Marl Bank HILL’* where slaves dug out 
marl during Civil War days* It is located on 
the CREMONA plantation adjoining the DE LA BROOKE 
plantation* We were taken there by Mr*Cusick. 
Main exposure consists of white sands (fine) with 
oyster and pecten shells,etc. This is overlain 
by iron-brown colored sands which probably owe 
their coloring to pec elating water* Hlevat/iion 
of white sand layer in Marl Bank Hill* 77 feet 
above sea level* 
We found this same sand layer on road cut 
Northwest of Benedict ,Hd., on main road; a fine 
white sand layer overlain by iron-brown colored 
sands, and above it the Sunderland Pleistocene 
formation* Elevation of white sand layer at 
this place is 157 feet. 
The Sunderland Pleistocene formation can 
always be recognized by presence of numerous 
worn pebbles. 
In moring of August 20, I waited the arrival of 
the Nat^Museum truck at Governors Him. Collection 
loaded about noon. __ 
In afternoon Dryden and I visited Hollin Cliff 
on the Patuxent River* The base of the Calvert 
formation, that is the Diatomaceous deposit is 
exposed in this cliff. It is cappdd by an 
extremely hard indurated layer about 18 > inches 
in thickness, and this contains numerous oyster 
shells and a few pectens. 
Above this hard layer is the Pleistocene 
Sunderland formation^. JS
