- Figure 1. Map showing location of
the upper Yellowstone River area, Montana
- Figures 2-5. Graphs showing:
- 2. Cross section 71,
which is typical of a location in the lower study reach with multiple
channels and a wide flood plain
- 3. Cross section 90,
which is typical of a location in the lower study reach where the channel
is incised and the flood plain is narrow
- 4. Cross section 149,
which is typical of a location in the upper study reach with a bridge and
pier

profiles for selected reaches of the Upper Yellowstone River, Montana
