A gravel covered plain is called a Reg. A reg is a desert basin where the sand has been blown away leaving a gravel covered plain.
To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.
The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:
Step 1: Subtract the time of P wave arrival from S wave arrival.
Step 2: See what the time difference is equal to in distance on a seismic wave chart.
Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.

Answer:
the Alaska Range and the Brooks Range
Explanation:
Alaska is a federal state in the United States. It is actually the largest state of this country, and it is also the northernmost state. All of Alaska lies on very high latitude, thus it has very cold climate for much of the year.
Big portion of the landscape of Alaska is covered by two mountain ranges. These mountain ranges are the Alaska Range and the Brooks Range. Both ranges have a roughly west to east direction.
The Alaska range is located in the southern and southeastern part of Alaska. It alleviates immediately from the coastline. It separates this part of the country and the lowlands of the interior.
The Brooks Range is located between the central part of the state and the norther part of the state, being a natural boundary between the two parts. This range lifts high up between the lowlands in the interior, and the lowlands in the northern part of the state.
