Yocum Falls, is a waterfall located in the heart of the Mount Hood National Forest, in Clackamas County, in the U.S. state of Oregon.
 It is located in a privileged area in Zigzag canyon with several waterfalls including Little Zigzag Falls and Ramona Falls.
 The name, as well as Yocum Ridge, the south ridge of the Sandy Glacier on the west slope of Mount Hood, comes from businessman Oliver C. Yocum.
Wrenn Peak ( ) is a peak rising to 1750 m on the ridge at the head of Sandy Glacier and Enyo Glacier in Olympus Range, McMurdo Dry Valleys.
 Named by Advisory Committee on Antarctic Names (US-ACAN) (2004) after John H. Wrenn, Department of Geology, Northern Illinois University, DeKalb, IL, a participant in the McMurdo Dry Valleys Drilling Project, 1973–74.
The Sandy Glacier Caves are a system of glacier caves within the ice of Sandy Glacier on Mount Hood, Oregon.
 They are thought to be the largest glacier caves in the lower 48 states of the U.S.A. Surveys done in 2011 and 2012 have measured the system at over 1 mile in length.
 The caves formed from internal glacial melting.
 As melting continues, the caves grow larger with entrances to the caves receding up the glacier's slope.
 Eventually it is predicted the caves will be completely gone within 7 to 10 years once the interior melting has reached the surface of the glacier.
Sandy Glacier is an alpine glacier located on the west slope of Mount Hood in the U.S. state of Oregon.
 It extends in elevation from about 8800 to .
 The glacier is the source of Muddy Fork, a tributary of the Sandy River.
 The upper extent of the glacier is known for extensive crevasses.
 The lower extent is marked by the Sandy Glacier Caves, possibly the largest glacier cave system in the lower 48 U.S. states.
Mount Hood, called Wy'east by the Multnomah tribe, is a potentially active stratovolcano in the Cascade Volcanic Arc of northern Oregon.
 It was formed by a subduction zone on the Pacific coast and rests in the Pacific Northwest region of the United States.
 It is located about 50 mi east-southeast of Portland, on the border between Clackamas and Hood River counties.
 In addition to being Oregon's highest mountain, it is one of the loftiest mountains in the nation based on its prominence.
The Chhota Shigri Glacier lies on the northern slope of the main ridge of the Pir Panjal Range of the inner Himalayas, east of the Rohtang Pass (H.P.).
 The high, steep ridges and mountain terrain provide an ideal condition for the development of this glacier.
 The Chhota Shigri Glacier is located at , covering about 16 sqkm area.
 The total drainage area of Chhota Shigri Glacier stream is approximately 35 sqkm .
 There is very high gradient from accumulation zone to ablation area and snout.
 The glacier meltwater drains out in a single confined stream and meets the Chandra River.
 Lateral moraines are present all along the body of the glacier up to the accumulation zone.
 This glacier is one of the best recorded in terms of mass budget studies among the other glaciers in the entire Himalayan region.
 Since 2002, Jawaharlal Nehru University in New Delhi is monitoring the glaciers for its mass balance and different hydrological aspects on an annual basis.
The Success Glacier is a small glacier located on the southwestern slopes of Mount Rainier in Washington.
 It covers 0.3 sqmi and contains 500 million cubic ft (14 million m) of ice.
 The glacier is bounded to the northwest by the Success Cleaver and to the east by the Kautz Cleaver.
 Starting from a steep rocky slope at about 11000 ft , the glacier flows southward downhill.
 At around 9000 ft , a small snowfield joins this glacier with the Pyramid Glacier to the southwest.
 Soon after this point, the glacier joins the adjacent Kautz Glacier at 8600 ft .
 The joined glaciers flow until their terminus at about 6000 ft .
 Meltwater from the glacier drains into the Nisqually River.
Muddy Fork is a tributary, about 6 mi long, of the Sandy River in the U.S. state of Oregon.
 Arising at the base of Sandy Glacier on the west slope of Mount Hood, it flows west through the Mount Hood Wilderness in the Mount Hood National Forest.
 It joins the Sandy River in Old Maid Flat, about 5 mi northeast of Rhododendron.
 The stream offers limited fishing for coastal cutthroat trout.
Enyo Glacier ( ) is a south-flowing glacier 0.6 nmi long situated east of Sandy Glacier in the eastern part of the Olympus Range, in the McMurdo Dry Valleys of Antarctica.
 In association with the names from Greek mythology grouped in this area, it was named by the New Zealand Geographic Board in 1998 after Enyo, a goddess of war.
The Wintun Glacier is a glacier situated on the eastern flank of Mount Shasta, in the U.S. state of California.
 It is both the third largest and third most voluminous glacier in California after the neighboring Hotlum Glacier and the Whitney Glacier.
 The Wintun Glacier starts on the east side of Mount Shasta's main summit, and it has the highest permanent snow and ice on the mountain, reaching above 14100 ft to within a few dozen feet (~8–15 m) of the true summit.
 The glacier flows east down a steep slope and terminates in two lobes, the longer of which extends down near 9800 ft .

Question: In which slope of Wy'east the Sandy Glacier is located on?
Answer: west slope
