Approaching a Hill

When you approach a hill, you need to decide if it

is one of those hills that is just too steep to

climb, descend, or cross. Steepness can be hard

to judge. On a very small hill, for example,

there may be a smooth, constant incline with only

a small change in elevation where you can

easily see all the way to the top. On a large hill,

the incline may get steeper as you near the

top, but you may not see this because the crest of

the hill is hidden by bushes, grass or shrubs.

Here are some other things to consider as you

approach a hill.

• Is there a constant incline, or does the hill get

sharply steeper in places?

• Is there good traction on the hillside, or will

the surface cause tire slipping?

• Is there a straight path up or down the hill so

you will not have to make turning maneuvers?

• Are there obstructions on the hill that can block

your path, such as boulders, trees, logs, or

ruts?

• What is beyond the hill? Is there a cliff, an

embankment, a drop-off, a fence? Get out

and walk the hill if you do not know. It is the

smart way to ﬁnd out.

• Is the hill simply too rough? Steep hills often

have ruts, gullies, troughs and exposed

rocks because they are more susceptible to

the effects of erosion.
