Creative Rationale

High in the Andes of Peru, where the thin air creates dramatically low atmospheric pressure, this composition channels Joan Mitchell's emotional response to extreme altitude and pristine mountain atmosphere. The cold temperature and high humidity suggest mist and cloud formation at elevation, while the calm winds and absence of precipitation create space for gestural marks to breathe and cluster organically. The luminous ground reflects the high pressure gradient and crystalline mountain light, with cool blues and steel grays dominating the palette, punctuated by warmer passages that recall distant valleys below.
