(CNN) — A ranger at Yosemite National Park is pleading to visitors to drive slow and stay alert after another bear was killed by a car.

The ranger said the female cub that was hit by the car couldn't have been more than six months old.
The ranger suspects it was common area for a bear crossing since there was another bear hit by a car in the same area.
The ranger stated that the mama bear kept calling out to the cub and the calls "sounding more pained each time."
The plea by the ranger comes as the park is in peak season for visitors -- June through September are the park's busiest months.
So far this fiscal year, the park has seen over 1.1 million recreational visitors, according to the park's report from May. »
