Al río / To the River is a large-scale photographic project that depicts the river, Río Bravo/Rio Grande, which is used to demarcate the international boundary between Mexico and the United States. Since 2016, Leonard has photographed along the 2,000-km stretch of river that acts as the border between the two countries, mapping the river’s journey through the cities of Ciudad Juárez, Mexico and El Paso, Texas, and onto the Gulf of Mexico. Comprising of hundreds of images, Leonard’s nuanced and complex portrait of the river reflects its broader role as a site of agriculture, commerce, culture, policing and surveillance.
