Dragon of Icespire Peak: Tower of Storms cliff heights

The text for this location says the rock outcrop upon which the Tower stands is 80 feet above the water, while the causeway out to the outcrop is only 5 feet above the water. The slopes of the outcrop can be climbed, but they are slippery. Should a PC slip and fall, per the falling rules, they take 1d6 per 10 feet fallen.

However, there are no indicators on the map to show how high a given point between the outcrop plateau and the causeway is above the water. Does anyone have a version of the map that fixes this?
