Guam is how many miles long

The entire northern half is a shelving, more or less flat, plateau of metamorphosed coral limestone, a terrace atop a submerged volcanic base. The limestone plateau is interrupted only by Mt.

Santa Rosa rising to elevation feet from feet m. The tofoot cliffs bounding the plateau are very abrupt, nearly vertical, with only occasional breaks. The southern half of Guam is mountainous and largely basaltic, a "volcanic massif which has burst through the coralliferous limestone" Alexander Agassiz.

Remnants of limestone formations as old as Miocene over seven million years ago are found occasionally, at considerable elevations, in the volcanic mountains of the southern half.

Guam has been gradually and repeatedly elevated, apparently with submergences intervening. The highest point on Guam is Mt. Lamlam, in the southwest, elevation feet.

The tropical warm ocean with a myriad of blue-aqua-green water is magnificently viewed from the limited coastal plains or the many heights above the coasts. Guam is not particularly high, with Mt. Lamlam being the highest point at 1, feet. The various topographic regions make it seem large and many people live and work away from the coasts.

While the private economic sector is expanding, federal and local governments are the largest employers in this unique organized unincorporated US territory. By Bruce G. Karolle, PhD. Karolle, Bruce G. Townsville: James Cook University, Guampedia image.
