#### Answer

Point Success: $14,164$ feet
Rainier: $14,416$ feet
Matlalcueyetl: $14,636$ feet
Steele: $16,624$ feet
McKinley: $20,237$ feet

#### Work Step by Step

To sort the mountains from shortest to tallest, we first take the absolute value of the "altitude" column, and then arrange the numbers from smallest to largest:
Point Success: $|14,164|=14,164$ feet
Rainier: $|14,416|=14,416$ feet
Matlalcueyetl: $|14,636|=14,636$ feet
Steele: $|16,624|=16,624$ feet
McKinley: $|20,237|=20,237$ feet
(Here the absolute value does not change the values, as all the numbers are already positive.)
