Abstract

This paper presents atomated monitoring of rock joint widening and temperatures, in autumn and spring, on 3 rock outcrops around Mount Ainodake, in the Akaishi Range, southern Japanese Alps, where a series of field observations on frost weathering have been undertaken in 1990, 1994 and 1999. The data analysis focuses on the timing and magnitude of joint widening (frost wedging) in relation to subzero rock temperatures and frost penetration depth. The temperature range at which wedging occurs varies with the bedrock conditions, water avaibility and duration of freezing
