Parallel high-frequency reflectors typical of varved
glacial Lake Barlow silty clays characterize the older succession (Shilts 1984), which is overlain by a largely transparent, reflector-free Holocene succession.

The role of biogeochemical cycling for the formation and preservation of varved

The till is overlain by glaciolacustrine sands, silts or varved
clays, up to 25 m in thickness.
Both these sites are located on the riverbank where varved
clays underlie the studied deposits and landslides are quite common, thus one can suspect that these deposits are not in situ position.
Water movement has been exclusively through fractures and along varved
bedding planes for approximately 700,000 years, indicating that in these settings, matrix flow is not occurring.
