'This book outlines the ways in which the imaginative geography of the Himalayas was constituted by western scientific knowledge, indigenous cosmologies and labour in the nineteenth century contributing to a global science of mountains. Here East India Company surveyors and naturalists jostle with Bhotiya and Tatar mountain guides, their multiple narratives framed through an interdisciplinary lens of botany, biogeography, glaciology, and anthropology. This is environmental history at its best.' Vinita Damodaran, University of Sussex
