Passage: There are over 20 miles (32 km) of hiking trails at Worlds End State Park. Most of the trails are rocky and steep, so hikers are encouraged to wear proper footgear and to be prepared for icy conditions during the cold winter months. As John Young writes in Hike Pennsylvania, "If you want to do some hiking in the Worlds End region, you should know that hiking here means climbing". Worlds End State Park is open during the winter months for snow mobiling and cross-country skiing. Most of the trails are too steep or rugged for either activity, but the park roads are open, as are trails on surrounding state forest lands.
Loyalsock Trail, often abbreviated LT, is a rugged 59.28-mile (95.40 km) hiking trail that stretches from near Loyalsockville, in Lycoming County on Pennsylvania Route 87 to north of Laporte in Sullivan County, just off U.S. Route 220. This trail follows the ridges and streams of the Loyalsock Creek watershed. The trail is primarily within the boundaries of Loyalsock State Forest and uses some old logging roads and abandoned railroad grades. The Loyalsock Trail was originally blazed in a yellow rectangle with a red stripe, and red can lids with a yellow "LT". Recently, the trail markers have been changed to a yellow disc with a red "LT".
Link Trail is a moderate 8.5-mile (13.7 km) trail marked with a red X on a yellow circle blaze. The trail starts at the Cabin Bridge in the park and follows Loyalsock Creek before it branches off and follows Double Run. The trail then ascends to Canyon Vista and heads out into Loyalsock State Forest where it links up with the Loyalsock Trail at the 55.33-mile (89.05 km) post. The Loyalsock Trail can be followed back for a 17.62 miles (28.36 km) long loop.
Canyon Vista Trail is a 3.5-mile (5.6 km) loop trail with blue blazes that passes through the eastern portion of the park and a stand of ash, sugar maple, and black cherry trees. This trail passes a maze-like jumble of blocky Pottsville Formation rocks known as the Rock Garden, adjacent to Canyon Vista. The vista is at an elevation of 1,750 feet (530 m) and "rewards the hiker with a spectacular view of the Loyalsock Creek gorge".
Worlds End Trail is a 3.25-mile (5.23 km) trail with yellow blazes that begins at the park office and ascends to an overlook of the swimming area. It then crosses the old Pioneer Road, which was used by some of the first settlers to the area, and enters the Loyalsock State Forest, ending at the 37.77-mile (60.78 km) post of the Loyalsock Trail, which can be followed back to the park office to make a loop 11.5 miles (18.5 km) long.
Butternut Trail is a 2.5-mile (4.0 km) trail marked with orange blazes that loops through a hardwood forest and crosses over Butternut Run. Two side trails connect Butternut Trail with the Loyalsock Trail. 
Question: What is the name of the trail that crosses Pioneer Rock?

Ex Output:
Worlds End Trail.

Passage: In 1891 the Great Northern Railway crossed the Continental Divide at Marias Pass 5,213 feet (1,589 m), which is along the southern boundary of the park. In an effort to stimulate use of the railroad, the Great Northern soon advertised the splendors of the region to the public. The company lobbied the United States Congress. In 1897 the park was designated as a forest preserve. Under the forest designation, mining was still allowed but was not commercially successful. Meanwhile, proponents of protecting the region kept up their efforts. In 1910, under the influence of the Boone and Crockett Club, spearheaded by Club members George Bird Grinnell, Henry L. Stimson, and the railroad, a bill was introduced into the U.S. Congress which redesignated the region from a forest reserve to a national park. This bill was signed into law by President William Howard Taft on May 11, 1910. In 1910 George Bird Grinnell wrote, "This Park, the country owes to the Boone and Crockett Club, whose members discovered the region, suggested it being set aside, caused the bill to be introduced into congress and awakened interest in it all over the country".
From May until August 1910, the forest reserve supervisor, Fremont Nathan Haines, managed the park's resources as the first acting superintendent. In August 1910, William Logan was appointed the park's first superintendent. While the designation of the forest reserve confirmed the traditional usage rights of the Blackfeet, the enabling legislation of the national park does not mention the guarantees to the Native Americans. It is the position of the United States government that with the special designation as a National Park the mountains ceded their multi-purpose public land status and the former rights ceased to exist as it was confirmed by the Court of Claims in 1935. Some Blackfeet held that their traditional usage rights still exist de jure. In the 1890s, armed standoffs were avoided narrowly several times.The Great Northern Railway, under the supervision of president Louis W. Hill, built a number of hotels and chalets throughout the park in the 1910s to promote tourism.  These buildings, constructed and operated by a Great Northern subsidiary called the Glacier Park Company, were modeled on Swiss architecture as part of Hill's plan to portray Glacier as "America's Switzerland". Hill was especially interested in sponsoring artists to come to the park, building tourist lodges that displayed their work.  His hotels in the park never made a profit but they attracted thousands of visitors who came via the Great Northern. Vacationers commonly took pack trips on horseback between the lodges or utilized the seasonal stagecoach routes to gain access to the Many Glacier area in the northeast. 
Question: What was the full name of the Great Northern Railway president?

Ex Output:
Louis W. Hill.

Passage: As Harvey's interests shifted to the Pyramid, Monte Ne's resort days effectively ended and the number of visitors slowly dwindled. Activities and events at Monte Ne continued, supported by locals who still visited in large numbers. Harvey sold the Hotel Monte Ne. The hotel went through several name changes and owners, becoming the White Hotel circa 1912, the Randola Inn in 1918, the Hotel Frances in 1925, and in 1930 the Sleepy Valley Hotel. Monte Ne's larger hotels continued to be active after they, along with the dance pavilion and Elixir Spring, were foreclosed and sold at public auction. From 1927 to 1932, Missouri Row and Oklahoma Row (often called the Club House Hotels at this point) were home to the Ozark Industrial College and School of Theology, a nonsectarian school run by Dan W. Evans. The hotels housed pupils—Missouri Row for boys, Oklahoma Row for girls—and Oklahoma Row also provided classroom and dining spaces. Evans and his family lived in the tower. The dance pavilion was enclosed and served as the school chapel. In May 1932, following a mortgage foreclosure against the school, school officials were evicted and the property was sold.After he announced the building of the Pyramid, at age 69, Harvey began suffering a series of serious health problems, but continued to work tirelessly. In 1926, blood poisoning in his foot put him in a coma that lasted several days resulting in surgery, and three months of recuperation. In 1929 he and Anna were finally divorced. Three days later Harvey married his long-time personal secretary May Leake. In 1930, he came down with double pneumonia. He was also going blind and needed younger people to read his letters and the newspaper to him. 
Question: What was the full name of the person who lived in the tower with his family?

Ex Output:

Dan W. Evans.
