They took trained Alpine guides and surveyors including Grant Peterkin and Surjan Singh, whose contributions ensured that, unlike numerous other maps the Workmans helped create, their map of the Siachen Glacier remained unchallenged for many years.
Nesta expedición acompañáronos guías e exploradores alpinos entre os que se atopaban Grant Peterkin e Surjan Singh, cuxa contribución asegurou que, ó contrario que moitos outros dos mapas que os Workman axudaran a crear, o seu mapa do glaciar Siachen se mantivese indiscutido durante moitos anos.
