What is the name of the place whose sister park is on the west rim of the gorge?  Answer the above question based on the context below:  Leonard Harrison State Park is a 585-acre (237 ha) Pennsylvania state park in Tioga County, Pennsylvania, in the United States. It is on the east rim of the Pine Creek Gorge, also known as the Grand Canyon of Pennsylvania, which is 800 feet (240 m) deep and nearly 4,000 feet (1,200 m) across here. It also serves as headquarters for the adjoining Colton Point State Park, its sister park on the west rim of the gorge. Leonard Harrison State Park is known for its views of the Pine Creek Gorge, and offers hiking, fishing and hunting, whitewater boating, and camping. The park is in Shippen and Delmar Townships, 10 miles (16 km) west of Wellsboro at the western terminus of Pennsylvania Route 660. Pine Creek flows through the park and has carved the gorge through five major rock formations from the Devonian and Carboniferous periods. Native Americans once used the Pine Creek Path along the creek. The path was later used by lumbermen, and then became the course of a railroad from 1883 to 1988. Since 1996, the 63.4-mile (102.0 km) Pine Creek Rail Trail has followed the creek through the park. The Pine Creek Gorge was named a National Natural Landmark in 1968 and is also protected as a Pennsylvania State Natural Area and Important Bird Area, while Pine Creek is a Pennsylvania Scenic and Wild River. The gorge is home to many species of plants and animals, some of which have been reintroduced to the area. Although the Pine Creek Gorge was clearcut in the 19th and early 20th centuries, it is now covered by second growth forest, thanks in part to the conservation efforts of the Civilian Conservation Corps (CCC) in the 1930s. The park is named for Leonard Harrison, a Wellsboro lumberman who cut the timber there, then established the park, which he donated to the state in 1922. The CCC improved the park and built many of its original facilities. Since a successful publicity campaign in 1936, the park has been a popular tourist destination and attracts hundreds of thousands of visitors each year. Leonard Harrison State Park...
