Approaching the Divide
As we approach the Continental Divide, we reach the southernmost foot hills of the Tetons where the ridges fall off and scatter in disarray. Essex Mountain provides a last pinnacle overlooking the Killpecker Dunes, beyond which the Great Divide Basin spreads out like a dry ocean floor. Its appearance may be the result of its nature as an endorheic basin into which rain falls but instead of running off, it drains directly into the earth. The landscape of the basin is pockmarked and ringed by the slowly draining and evaporating water.
