KODACHROMEBY NATIONALGEOGRAPHICPHOTOGRAPHERROBERTF. SISSON © N.G.S. Whirling in for a landing, a helicopter delivers a work crew to the Freeport Sulphur Company's mine in the Gulf of Mexico. A derrick tops the production platform where Freeport expects to work 108 wells. Large pipes beneath the ramp carry hot water to melt the sulphur in its limestone bed below the Gulf; smaller ones return liquid sulphur to a depot where it is pumped seven miles under the sea to Grand Isle. For this first deepwater sulphur mine, Freeport has built a town on platforms, 718 with offices, a 60-room dormitory, recreational lounges, and cafeteria-all air-conditioned.
