Pat Shingleton: "Jefferson, Lewis, Clark..."
Thomas Jefferson recorded weather events on a daily basis. When Meriwether Lewis and William Clark began their expedition of discovery to the Pacific Ocean, President Jefferson made sure they were well supplied. Along with the best Kentucky rifles, powder horns and 400 pounds of lead shot, their supplies included portable soup, fish hooks, mosquito netting, flints, the finest instruments of navigation, a microscope, colored beads and cloth for trading. In addition to charting new territories, Lewis and Clark also made numerous contributions to science. They discovered a variety of flora and fauna unknown to science at that time. Their journals noted accomplishments in botany and zoology. They also transported three thermometers on their trip into a portion of America where meteorological observations had never been reported. Their notations included the number of rainy, cloudy and clear days along with lightning, snow, hail, ice, seasonal prevailing winds and plants and animals reactions to the elements.
