A group of Earth science students decided to take an adventurous camping trip, so they rode bicycles to a
state park that was located in an isolated area. They traveled up a steep hill. When they reached the top,
they looked at the landscape and noticed a lake at the bottom of the hill. They named it Hidden Lake. To
the left of Hidden Lake was a large field with a small stream. They decided to set up their campsite in the
field near Hidden Lake. To get to the field, they cycled down a very steep slope.
The map below shows the location of the bicycle trail and the students' campsite. Points P and Q are
reference points on the map.
18. State the evidence shown on the map that indicates that the area directly north of Hidden Lake is relatively
flat.
