Nuevo Leon, Mexico: Sierra Madre Oriental (near Monterey) formed about 60 million years ago, when one of the crustal plates of the Pacific collided with what is now western Mexico. Beneath the massive limestone layers, which are now buckled up into the ridges of the Sierra, were thick layers of rock salt and other evaporite minerals. Salt behaves plastically when even minor stress is applied; here it has allowed the overlying slabs of rigid rock to rumple like a rug and has flowed into the cores of the steep-sided ranges.

Himalayan foothills: Uncommonly sharp view of the southern Himalayan foothills that illustrate drainage adjustments to the ongoing uplift of the mountains and clearly delineate deforested areas.

Potrero Garcia and Potrero La Mula: Potrero Garcia and Potrero La Mula are breached salt-cored folds immediately north of the Sierra and Monterey. Individual limestone layers can be resolved in this beautifully detailed view, as can the tilt of the layers outward from the center of the fold (anticline). Most of the salt has been eroded from the core of the structure, but what remains is now being mined. In Las Grutas de Garcia (Garcia Caverns) the limestone bedrock has been dissolved and both limestone and gypsum formations decorate the cave.

Hangduan Shan range, Yulongxue Shan: Yulongxue Shan (Hangduan Shan range, western Yunnan Province, near the India/ Burma/China border junction). One of many south-trending mountain masses in this region, Yulongxue Shan rises to 18,800' and the course of the Yangtze River is sharply deflected around the prominence. As with the main ranges of the Himalaya, these have been uplifted in response to the collision of India with the Asian continent; along the eastern margin of the Indian block, the trend of the ranges changes from easterly to southerly. There is also lateral movement on the long, steeply inclined faults bounding the ranges, as blocks are crowded out to the southeast during the continued northward march of India.
