Detailed Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Problem:Passage: By 1875 Ricketts had named the tallest waterfall on Kitchen Creek Ganoga Falls, and in 1881, he renamed Long Pond as Ganoga Lake. Pennsylvania senator Charles R. Buckalew suggested the name Ganoga, an Iroquoian word which he said meant "water on the mountain" in the Seneca language. Donehoo's A History of the Indian Villages and Place Names in  Pennsylvania identifies it as a Cayuga language word meaning "place of floating oil" and the name of a Cayuga village in New York. Whatever the meaning, Ganoga Lake is the source of the branch of Kitchen Creek that flows through Ganoga Glen, which has the tallest waterfall.A dam was built upstream of the waterfalls on the Ganoga Glen branch of Kitchen Creek in 1842. Ricketts strengthened the dam circa 1905 as part of a hydroelectric power generation scheme, and renamed the body of water Lake Rose (Rose is a Ricketts family name). However, both the Lake Rose and Lake Leigh dams were "poorly constructed" and could not be used to generate power; both dams were condemned by the state and Lake Rose was drained in 1969. Ganoga Glen is not as steep as Glen Leigh; both glens are almost entirely in the Huntley Mountain Formation, with a small region at the southern end, including Waters Meet, in the Catskill Formation.
 
Ganoga Glen has ten named waterfalls in 1.1 miles (1.8 km). It is 1.8 miles (2.9 km) from PA 118 in the south to Waters Meet and the southern end of Ganoga Glen. From the north, it is 0.3 miles (0.48 km) from the Lake Rose trailhead parking lot by Lake Jean to Mohawk, the northernmost waterfall. There is also the 2.8-mile (4.5 km) Ganoga View Trail, which leads from Pennsylvania Route 487 in the west to Ganoga Falls. The Highland Trail, which meets the Falls Trail a short distance north of Mohawk Falls, is the 1.2-mile (1.9 km) connector between the northern ends of Ganoga Glen and Glen Leigh.Jeff Mitchell writes in Hiking the Endless Mountains: Exploring the Wilderness of Northeast Pennsylvania that Ganoga Glen has his "favorite place" in the park: "Here the trail wraps around ledges and underneath overhanging rocks, right next to the waterfalls. The roar of the falls reverberates against their rocky confines. The state park trail map says that Seneca, Delaware, and Mohican Falls are here, but it is hard to discern which falls are which because they explode from everywhere and are continuous.".
