>Dear Bruce and Colleagues,

Such an event is becoming all-too-common 
world-wide. There are three obvious reasons for 
outcrop desecration:

1. Commercial gain by individuals and companies, 
Beautiful/rare/perfect minerals, mineral 
aggregate, fossils, and rock structures are 
always at risk. The worst example of this with 
which I am familiar is the removal of slabs of 
wonderfully weathered and etched slabs of lower 
Carboniferous fossiliferous carbonates from Hook 
Head, Co Wexford, Ireland. This is quite shocking 
and inexcusable and should be made illegal; the 
US has more advanced laws in this regard than any 
other nation.

2. The collection of aesthetically-pleasing, 
beautiful, and teaching specimens by individuals, 
departments, and Museums. I suspect that most of 
us have done this to some extent (I certainly 
have) There are "admirable" reasons for the 
collecting but little thought given to the fact 
that future generations will not have the 
intellectual and aesthetic benefit of seeing the 
great classic outcrops of the world in their 
pristine condition.

3. The collection of specimens for valid research 
reasons. If geology is to progress, specimens 
have to be collected for laboratory analysis. 
However, classic, beautiful outcrops need not be 
wrecked. A particular example is the drilling of 
the wonderfully washed and polished rocks of the 
Komati river section in the Barberton Mountain 
Land in South Africa. Another is the drilling of 
the KT boundary section in Woodside Creek in the 
Seaward Kaikouras in the South Island of New 
Zealand. Te perpetrators of these drillings are 
known. Generally, adjacent outcrops can be 
sampled even with rock saws and drills and 
satisfactory samples can be collected. Commonly, 
people want the quick, easy, lazy, and dirty 
solution, and attack the best, most 
easily-accessible and exposed outcrops.

Collecting should be discouraged by Societies, 
and University geology departments. The GSA 
should put out a directive.Most of it is 
unnecessary. Knocking off a bit of rock, and 
collecting the odd fossil or mineral is, perhaps 
, acceptable provided that classic outcrops are 
not ruined but the use of a rock saw or rock 
drill on "top" outcrops is unacceptable and must, 
somehow, be banned. Exposure of perpetrators, 
expulsion from professional societies and 
organizations, and massive fines are minimal 
"solutions". The rock saw vandalism of  the 
Bartlett Wash deformation bands is  surely by 
someone or a group doing research on deformation 
bands; he, she, or they should not be too hard to 
trace. The Federal and State Authorities should 
pursue this vigorously and prosecute to the full 
extent of Federal and State Law. The geological 
profession needs to be vigilant in preventing, 
reporting, and exposing outcrop vandalism.

Best wishes,
John Dewey
