mountain was renovated, receiving new paint externally and some repairs internally. The vehicle seating arrangement was also modified to accommodate a single passenger in each seat rather than a lap-sitting arrangement of two riders. This resulted in three individual seats within each bobsled, with two cars linked for a total of six guests, similar to the configuration of the trains at Walt Disney World's version of Space Mountain. The new bobsleds were painted red, blue and green, and the ride reopened on June 15, 2012. As a result of the new trains, the height requirement was raised to 42 in (107 cm) from the original 35 in (89 cm). Other smaller changes were made, including the addition of wooden fences on the catwalks and a single-rider lane. The main Abominable Snowman animatronic at the top was given a moveable jaw, and the main roar was now much louder. It was toned back down around October of that year. The entire mountain exterior received a facelift. For only the second time—the first since when the attraction was originally built—scaffolding was erected all the way from the base of the mountain to the top. The mountain had been repeatedly repainted through the years, resulting in a mostly white Matterhorn mountain with the appearance of snow; but in 2012, the entire mountain was made bare again and carefully painted in a style more faithful to the look of the real Matterhorn, with more "snow" places on the northern side and less on the southern. For the first time since the Matterhorn's early days, the mountain's base was mostly snowless. In the past, the "snow" on the mountain's surface was merely white paint; for the refurbished ride, glass beads were mixed into the paint to reflect sunlight like real snow. Imagineer Jim Crouch was the rehab's art director. The "mountain climber" performers also returned after the refurbishment. On January 5, 2015, the attraction was closed for an extended refurbishment to prepare for the park's 60th anniversary. It reopened on May 22, 2015, with new special effects and updated animatronics. On the lift hills, the snowfall projection was replaced with the Abominable Snowman peering through a sheet of ice as the bobsleds ascend. The artificial screaming at the top of the lift was also removed. The red eyes were removed, and replaced with the Snowman roaring with the sound that he’s pursuing the bobsleds. A
