Tsokar | Life and death . Tsokar lake lies the the Rupshu Valley in the Ladakh region of Jammu and Kashmir. The lake is surrounded by mountains and bog. It was hard to cross the bog to reach the lake, so the only other option was to walk around. We saw decomposing carcasses in the bog, of animals who may have got stuck , we also met a Changpa Nomad with seven horses, who was making his way across the valley.
