Gold Rush Supplies Read the Following Passage and Answer the Question(S)
Student Name: Grade 4 ELA Unit 5 Post Test with Computer Enhanced Questions(Teacher Edition) Assessment ID: dna.15359 ib.238392 Directions: Read the passage below and answer the question(s) that follow. Gold Rush Supplies Read the following passage and answer the question(s). Text 1 The following is from the diary of a miner, William Z. Walker from 1849. Mon. Sep. 10th The amount collected by the miners on Bear River was from $4 to $16 and sometimes even $50 per day. Each according to the luck of the miner. Supplies were very high here. Flour $40. per hundred, Pork and Bacon $1. per lb. Other things in proportion Gold–rockers were worth $40. Shovels $10. Picks $10. and so on. Walker, William Z.. Diary, 1849. September 1849, pages 135 – 137. Text 2 The following is from a textbook chapter on the California Gold Rush. During the California Gold Rush, some miners were more successful than others. Most miners earned $6 to $10 per day. But some miners in 1849 could dig $2000 a day! After striking it rich, some miners had a lot of money. This gave Sam Brannan, a store owner, an idea. He raised the cost of supplies for miners. In his greed he became rich without mining. He did not struggle like the miners. In his store, mining pans that were just 20 cents started to sell for $15. In different parts of the state, prices were high too. Miners paid different prices for flour. In September, flour was $50 per 100 pounds. A month later, miners paid $30 for the same flour, but in a different city. -

E-mail: [email protected] ABSTRACT: Progressive rock-fall failures in natural rock slopes are common in many environments, but often elude detailed quantitative documentation and analysis. Here we present high-resolution photography, video, and laser scanning data that document spatial and temporal patterns of a 15-month-long sequence of at least 14 rock falls from the Rhombus Wall, a sheeted granitic cliff in Yosemite Valley, California. The rock-fall sequence began on 26 August 2009 with a small failure at the tip of an overhanging rock slab. Several hours later, a series of five rock falls totaling 736 m3 progressed upward along a sheeting joint behind the overhanging slab. -

Principal Waterfalls of the World (1945) by C. Frank Brockman
Next: Introduction Principal Waterfalls of the World (1945) by C. Frank Brockman Cover with Nevada Fall • Cover (image) • Introduction • Yosemite Falls • Principal Waterfalls • Waterfalls Classified As to Height • Other Waterfalls Classified As to Height • Waterfalls of Volume and Power • References About the Author C. Frank Brockman was born June 4, 1902 in Cincinnati, Ohio. He graduated from Colorado State University in 1924 with a BS in Forestry. He worked in a variety of jobs, including with the US Forest Service. In 1928 he became a seasonal ranger at Mount Rainier National Park and became Park Naturalist later that same year, serving for 13 years. He began a number of field research projects, including measuring glacier movement and size. In 1913 he earned a MS in Forestry from University of Washington (UW). C. Frank Brockman was appointed Park Naturalist of Yosemite in 1941. Brockman wrote a number of articles on Park history and natural history and developed the park museum. Brockman resigned in 1945 to become Associate Professor of Forestry at UW, where he specialized in dendrology and recreational management. Brockman wrote multiple articles on forestry and the best-sellling Golden Guide to Trees of North America (Random House, 1968), which is still in print in a revised edition. He also wrote Recreational Use of Wild Lands (McGraw-Hill, 1959). The Brockman Memorial Tree Tour at UW is named for him, and he wrote the original guide book to the trees of the campus. Brockman died March 20, 1985 in Seattle, Washington. • “C. Frank Brockman,“ biography from Mt. Ranier National Park website • “C.
