The Department of Botany from the Smithsonian tells us that; “The Blue Mountains have a complex geology of both volcanic and marine influences. The rocks are igneous and sedimentary of origin with the soils being mainly siliceous.” They also state that the Blue Mountains are formed by, “a central ridge of metamorphic rock that runs northwest to southeast, from which many long spurs overhang to the north and south, for a distance of over 3 kilometers, the crest of the ridge exceeds 1,800 meters.” (Smithsonian)
The John Crow Mountains are the opposite, the Smithsonian states, “they are comprised of white limestone, marine sandstones and shale." Smithsonian)
It’s coordinates are located between the Latitudes 17°57'-18°12'N and longitudes 76°49'-76°16'W. This also includes the John Crow Mountains and the surrounding area of “crown land.” (Wikipedia 2007)
In 1990 both the Blue and John Crow mountains were preserved and celebrated as Jamaica’s first national park. Here the Nature Conservatory tells us that, “This protects one-third of approximately 30% of Jamaica that is still under natural forest cover.” They also say that, “it is the largest reaming tract of intact, closed canopy broadleaf forest left in Jamaica.” (Nature Conservatory 2007).
The Eastern part of Jamaica’s topography is steep and rugged. The landscape is geologically stated as, “being young (Quaternary.)” This part of the island is the most seismic and suggest to be undergoing g
