• Set chronological context: railroad 1863-1869 — after Mexican-American War, during/after Civil War

Direct teach 4-thread causation chain. THREAD 1: Federal land grants — Pacific Railway Act of 1862 (signed by President Lincoln during Civil War) granted approximately 175 MILLION acres of federal land to railroad companies (Central Pacific + Union Pacific). The federal land was Indigenous-nation homeland. THREAD 2: Chinese labor — approximately 15,000 Chinese laborers, predominantly from Guangdong Province in southern China, comprised about 90% of the Central Pacific workforce. They blasted through the Sierra Nevada granite, worked in winter snow drifts, and were paid less than white workers. They struck for better wages in 1867 (one of the largest labor strikes of the era). Read Stanford CSP age-adapted oral-history excerpt. THREAD 3: Indigenous displacement — the railroad route crossed homelands of Paiute, Shoshone, Goshute, Bannock, Ute, Lakota, Cheyenne, Arapaho, Pawnee. Treaties were violated; bison hunting from train windows accelerated the buffalo catastrophe. THREAD 4: Environmental modification — Sierra Nevada tunnel blasting; Great Plains grading; mass timber harvest; bison reduction. Show Andrew J. Russell 'East Meets West' photograph (May 10, 1869, Promontory Summit UT). Note the photograph contains railroad executives, soldiers, white workers — NO Chinese laborers, despite their 90% labor contribution to the Central Pacific. Naming this absence is part of learning. Today the Golden Spike National Historical Park interprets the railroad with Chinese-American-labor recognition (added in recent decades).

• Naming labor matters. The transcontinental railroad was a Chinese-laborer achievement (and an Irish-laborer achievement on Union Pacific) — not just a railroad-executive achievement.

  model Approximately 15,000 Chinese laborers, predominantly from Guangdong Province, were about 90% of the Central Pacific workforce. They blasted through the Sierra Nevada, worked in winter snow drifts, struck for better wages in 1867. They built the western half of the transcontinental railroad. Their names are mostly not in the historical record — Stanford CSP project is recovering them.

  prompt Who built the Central Pacific railroad?

• Name the 4 threads of the causation chain.
• Approximately how many Chinese laborers built the Central Pacific?
• Who is shown in the Andrew J. Russell photograph? Who is absent?

Apply MG-7 to Russell 'East Meets West' photograph: WHO took? Andrew J. Russell; WHEN? May 10, 1869; WHY? to document golden-spike ceremony; AGREE/DISAGREE with Stanford CSP oral histories? Russell photo is silent on Chinese labor; Stanford CSP makes it visible; CLOSE READ visual elements; WHOSE voice silent? Chinese laborers.

MG-12 displays Central Pacific (Sacramento east to Promontory) and Union Pacific (Omaha west to Promontory) routes with mile-by-mile labor identification overlay (Chinese laborer concentration on Central Pacific shown in red shading; Irish + African American + Civil War veteran concentration on Union Pacific shown in blue shading). Indigenous-nation displacement overlay shows nations whose homelands were crossed.

MG-12 Map

Transcontinental Railroad Route Map — May 1869 completion route from Sacramento CA east via Sierra Nevada (Central Pacific) to Promontory Summit UT, then east via Wyoming/Nebraska to Omaha NE (Union Pacific). Mile-by-mile labor identification: Central Pacific labor identified as ~15,000 Chinese laborers (approximately 90% of CP workforce) + Irish, German, formerly enslaved African American workers; Union Pacific labor identified as primarily Irish American + formerly enslaved African American + Civil War veteran workforce. Indigenous nations displaced by the railroad route shown in translucent overlay: Paiute, Shoshone, Goshute, Bannock, Ute, Lakota, Cheyenne, Arapaho, Pawnee — ALL sovereign nations TODAY. The 'Andrew J. Russell East Meets West' photograph location at Promontory Summit marked, with annotation 'No Chinese laborer is in this famous photograph despite their majority labor — naming this absence is part of learning.' Style: cartographic with explicit labor-and-displacement legend.
