ABSTRACT. To investigate recent glacier changes in the Himalayan region, we carried out GPS and ground-penetrating radar (GPR) measurements at Yala Glacier, a benchmark glacier in Nepal. Glacier surface elevation and ice thickness were surveyed along a 1. . Our results indicate that Yala Glacier has lost $40% of its ice volume over the last 27 years and that the rate of the mass loss has accelerated over the last decade
