FRAME 3-85. REVIEW FRAME.
How would you symbolize the following ford on a reconnaissance overlay?
It is the second ford to be symbolized, vehicular, and crosses a stream flowing at 2 meters per second, with no
seasonal limiting factors. It is 15 meters long, 5 meters wide, has a gravel bottom, and .75 meter deep at its deepest
point. The approach on the left bank is difficult; on the right bank it is easy. Draw the symbol below.
The fourth item in the route classification formula is the lowest overhead clearance along the route. If clearance
is unlimited, symbolize it by using 00 in the route classification formula
If any of the obstructions we have discussed in this lesson exist along a route, the letters (OB), in parentheses,
are shown n the route formula. Obstructions may be in overhead clearance or width constructions, slopes, curves,
ferries or fords.
The fourth item in the route classification formula is the lowest _______________________. The letters (OB)
in the formula indicates one or more ___________________________ along the route.
