The coal that exists in the mountains above Jim Thorpe is anthracite
coal. Anthracite is nearly pure carbon (about 86 percent) and is the
result of a process called coalification. The high carbon content of
anthracite makes it difficult to ignite. However, when it catches fire
it burns with a short, very hot, colorless, smokeless flame.
Coalification occurred in Eastern Pennsylvania as a result of the folding
and faulting in the formation of the Appalachian Mountains. These actions
caused intense pressures that produced the high carbon content found
in anthracite.
The anthracite deposits in Eastern Pennsylvania are divided into four
fields: north, south, east, and west. The coal fields above Jim Thorpe
are part of the southern field, the largest of the fields in northeastern
PA. The southern field extends 56 miles from Jim Thorpe to Lykens. Coal
is found in 141 square miles of this field.
