Signal Mountain in Grand Teton National Park is 7,727 feet tall. Signal Mountain Summit Road is a steep road that leads to the top. At the summit is a parking lot, overlook, restroom, and what appeared to be a cellular tower. It is also the only place in the park where I had 5 bars of service (AT&T).
There is a second overlook, Jackson Point Overlook, before you reach the summit of Signal Mountain, which is where the Signal Mountain hiking trail ends.
I drove up the road and watched the sunrise one morning. It was amazing. I also saw a bunch of deer which was really awesome!
