Alt Text Map of Golden Spike National Historical Park in Utah. Shaded in green, the park area winds along the Central Pacific Grade to reach the Last Spike Site and then a larger, zigzagging park area about two-thirds of the way across this wide map. Terrain is shown in beige and grades in red or blue. Extended Description This description will start in the west and move east. The West Grade Audio Tour begins near the left edge of the map and the East Grade Audio Tour begins in the second, larger park area to the right. A red line representing the Union Pacific Grade and a blue line representing the Central Pacific Grade curve down from near the top left corner of the map. Text near an arrow at the top edge where the blue line continues off the map reads, “Bureau of Land Management Transcontinental Railroad National Backcountry Byway (4-wheel-drive road).” A site between the two lines is marked “Camp Victory Site (Rozel)” and text that follows reads, “Central Pacific crews broke for lunch here in their race to lay the most track in one day.” A relatively short distance away and where the grades nearly meet is a blue callout box reading, “Begin West Grade Auto Tour, Closed December to May.” A note near the callout box reads, “Miles of track laid per day quickly became a contest between the two railroads. In early April the Union Pacific laid 8.5 miles of track in one day and then bet the Central Pacific $10,000 that they could not better the record. On April 28, 1869, the Central Pacific won the bet.” The line here alternates long blue dashes with short white ones, indicating that this section of the route is unpaved. The solid blue line picks back up near the Visitor Center. The grades travel first south and then east together. A spot marked in black on the Central Pacific Grade is labeled “A World Record” and text there reads, “Central Pacific crews finished their 10-Mile Day here, having laid 10 miles and 56 feet of track.” The grades travel between North Promontory Mountains and Promontory Hollow. A spot about halfway between the beginning of the West Grade Auto Tour and the Visitor Center Park Headquarters is labeled “Optional exit from tour route.” Now at the Visitor Center, which is at an elevation of 4,905 feet (1,495 meters) and has a picnic area, a golden spike symbol is labeled “Last Spike Site” and text reads, “Here at Promontory Summit the Union Pacific and Central Pacific rails were joined.” Farther into this square area of the park is the Engine House (locomotive winter storage). A note below reads, “To reach the West Grade Auto Tour, drive 7 miles west from the visitor center.” Golden Spike Drive travels north out of this section of the park and turns right to angle east and into the next section, which lies farther along the grades. Last Cut and Big Trestle Site are on the red line in this larger area of the park. Chinese Arch, Big Fill Loop Trail, which has a self-guiding trail, and Big Fill are on the blue line, which ripples slightly above the red. The Central Pacific Grade is partially unpaved in this section and both grades have a section of hiking trails after they pass Golden Spike Drive. Once out of the park, the grades turn northeast over text reading, “East of the Promontory Mountains, the Central Pacific and Union Pacific railroad grades crossed each other several times. In some places, they used the same grade.” The grades turn south just short of State Route 83, which continues north “To Interstate 84 and Boise, Idaho” off the top edge of the map and “To Interstate 15 and Brigham City” off the bottom edge. Golden Spike Drive continues southeast to cross both grades in the larger park area and meet State Route 83 near the lower right corner of the map. Another road branches off Golden Spike Drive to travel southeast to a picnic area and “To Promontory Point.” Legend A compass in the lower left corner of the map shows north angled slightly to the right. A scale next to it measures distances of 0.5 and 1 kilometers and 0.5 and 1 miles. The legend reads as follows: Green for Golden Spike National Historical Park, Line that alternates between long blue dashes and short white dashes for Auto tour route (unpaved), White line encased in black for Unpaved road, and Line alternating white and blue short dashes or white and red short dashes for Hiking trail. Two symbols represent Self-guiding trail and Picnic area.
