The philosophy of the storage of high-grade radioactive wastes in salt seems to be based on the assumption that the salt glaciers of Iran are no longer moving. Monitoring the movements of markers painted onto one of the salt glaciers suggests that the glacier deforms elastically as a result of temperature changes most of the time but flows plastically when it is sufficiently wet during each annual rainy season.
