79 feet above sea level

Answer 1

To determine the elevation of base camp, we start with Helene's initial elevation and then account for her descent.

1. Helene starts at an elevation of 33 feet above sea level.
2. She descends 46 feet.

We calculate the elevation of base camp as follows:

\[
\text{Elevation at base camp} = \text{Initial elevation} - \text{Descent}
\]
\[
\text{Elevation at base camp} = 33 \text{ feet} - 46 \text{ feet} = -13 \text{ feet}
\]

Since -13 feet indicates that base camp is below sea level, we can express this as:

\[
\text{Elevation at base camp} = 13 \text{ feet below sea level}
\]

Thus, the correct answer is:

**13 feet below sea level**.
