Figure 7. Ice-flow measurements at the Interstate 395/Parkway South interchange in Brewer (see Figure 4 for location). In this area, 64 flow indicators were measured (25 unique). Glacial maximum ice flow was southerly (red arrows). Then ice flow changed to the west-northwest toward the river lowland (280° azimuth vector mean, yellow arrows). Intermediate flow indicators are not observed between the two sets, suggesting a rapid change in flow direction. Base image is from Google EarthTM.
