4. The Old Spanish Trail, Southwestern US
The historic Old Spanish Trail once linked Santa Fe to Los Angeles, threading through the Rockies and Sierras over some of North America’s most challenging terrain. This network of mountain paths enabled early traders and migrants to traverse vast deserts and high passes, shaping the destinies of countless communities. Today, many segments of the trail are deserted, marked only by ancient petroglyphs and the crumbling ruins of missions and trading posts. These remnants evoke tales of resilience and exchange at remote mountain crossings. More information
