We report in situ measurements and field observations of dust devils at ~3800–4200 m elevation in the Argentine desert plateau (Puna). These first quantitative data at elevations where the ambient atmospheric pressure is only ~600–700 mbar support the notion that large and strong dust devils may be systematically more common in low‐pressure conditions, although regional meteorology and/or surface thermophysical properties may also contribute.
