Since the border crossing closure of May 2002, Mexican Nationals have been known to approach visitors from across the river to purchase souvenir items (walking sticks, bracelets, crafts, etc.) at certain river locations. If you agree to look at/or purchase their items and the Mexicans cross the river, they may be arrested for being in the U.S. illegally. They will be held until deported back to Mexico through Presidio (100 miles away). Mexican merchants will be arrested for illegal commercial operations which may result in a fine and/or additional incarceration while awaiting adjudication prior to deportation.
Items purchased will be considered contraband and seized by officers when encountered. Rocks, minerals, archeological items etc. cannot be purchased, imported, or possessed in the national park.
In addition, illegal trade impacts the resources of the park in a number of negative ways, including the creation of social trails, the cutting of cane along the river, erosion of riverbanks and an increased amount of garbage and contaminants along the Rio Grande watershed. Supporting this illegal activity contributes to continued damage of the natural resources along the Rio Grande, and jeopardizes the possibility of reopening the crossings in the future.
