Michael Yon is reporting for the New John Batchelor Show on the many thousands of people from scores of countries struggling through the Darien Gap in a desperate effort to get to the United States. Here's part one of his report, and here's part 2.
What is the Darien Gap? It's a hellhole for people traversing it. From an article at Dangerous Roads:
... The Darien Gap is a region of southern Panama that borders Colombia and is the only overland route into South America. ... It consists of a large watershed, forest and mountains. It’s possible to cross it. However to all intents and purposes at the time of this writing ... it is strictly off limits for the vast majority of travelers.
The barrier of the gap is partly natural due the dense rainforest that covers the region and over more recent years the significant safety concerns from guerilla activity have further reinforced this.
The gap is 50km wide, stretching from the Atlantic to the Pacific, and 96km long. Known as a drug smuggling corridor between the two countries, it’s rarely seen by outsiders. It’s a lawless wilderness teeming with everything from deadly snakes to antigovernment guerrillas. Tens of thousands of migrants a year risk their lives to cross it. ...
The Gap also represents a break in the Pan-American Highway -- a lethal break. Dangerous Roads notes that the few people who successfully make it on their own through the Gap are Special Forces types driving off-road vehicles. Even for the most experienced it's tough going. (See the photo at Dangerous Roads of two men with the Trans-Darien Expedition trying to push their off-road vehicle across the terrain).
The migrants who attempt the same journey are not Special Forces types and they travel on foot. They put their lives in the hands of guides who work for criminal gangs. Many of the migrants are murdered or die from the horrific rigors of the journey through the Gap.
