Cane Creek Mountains 300–350 million years ago during the formation and rifting of Pangaea. This earlier range is thought to have had peaks more than high, which would rival the Himalayas, the Andes, and the Alaska Range. However, erosion has worn this old mountain range down. The highest peaks of this old range are now found in the Appalachian Mountains on the eastern coast of North America and in the Anti-Atlas Mountains of Morocco in Africa. The heavily eroded hills of piedmont, including the Cane Creek Mountains, are remnants of the sizable mountain chain. The Cane Creek Mountains lie in the Carolina Slate
Seven Second Summits of at least 100 km to reach Mount Logan. In South America, Ojos del Salado involves a short scramble while Aconcagua is just a walk. Horrell acknowledged that Ojos del Salado was more technically difficult, but considered Aconcagua a greater challenge because of physical demands. Aconcagua's base camp, at 4,500 m, is accessible by mule, but from that point, climbers must carry all of their supplies to as many as three higher camps before the final ascent. By contrast, Ojos del Salado is accessible by four-wheel-drive vehicles to 5,200 m; from that point, climbers need only carry supplies to a
