Base your answer(s) to the following question(s) on the reading passage and topographic map below.
A group of Earth science students decided to take an adventurous camping trip, so they rode bicycles to a New York 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 eld with a small stream. They decided to
set up their campsite in the eld near Hidden Lake. To get to the eld, 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.
State the evidence shown on the map that indicates that the area directly north of Hidden Lake is relatively at.
