It was the first national park in the United States and, to most people around the world, the first known on the planet.
"The crowning achievement of the returning expeditions was helping to save Yellowstone from private development," writes the National Park Service.
"The wonders of Yellowstone — shown through Jackson’s photographs, Moran’s paintings and Elliot’s sketches — had captured the imagination of Congress. Thanks to their reports, the United States Congress established Yellowstone National Park just six months after the Hayden Expedition." It also features, most dramatically, more than half the world's known hydrothermal landmarks: geysers, hot springs, mudpots and steam vents.

If there was something coming, there is nothing to show at this point in time."Yellowstone is widely reported as the world's first national park.

Holocene climate and oceanography of the coastal Western United States and California Current SystemAbstract. Examination of climatic and oceanographic changes through the Holocene (11.75 ka–present) allows for an improved understanding and contextualization of modern climate change. Climate records of the Holocene can be utilized as a “baseline” from which to compare modern climate and can also provide insights into how environments experience and recover from change. However, individual studies on Holocene climate in the literature tend to focus on a distinct geographic location, a specific proxy record, or a certain aspect of climate (e.g., upwelling or precipitation), resulting in localized, record-specific trends rather than a comprehensive view of climate variability through the Holocene. Here we synthesize the major oceanographic and terrestrial changes that have occurred in the Western United States (bounded by 30 to 52∘ N and 115 to 130∘ W) through the most recent 11.75 kyr and explore the impacts of these changes on marine and terrestrial ecosystems. We present a novel spatiotemporal analysis of Holocene marine and terrestrial temperature, hydroclimate, and fire activity across the Early, Middle, and Late Holocene using a coded analysis of over 40 published studies. Following coded analysis of temperature, hydroclimate, and fire activity in the paper, we include a broader literature review of environmental change through the Holocene, including an examination of the impacts of multi-millennial climate trends on ecological communities. We find that the Early Holocene is characterized by warming relative to pre-Holocene conditions, including warm sea surface conditions, a warm and dry Pacific Northwest, a warm and wet Southwest, and overall spatial and temporal stability. In the Middle Holocene, these patterns reverse; this interval is characterized by cool sea surface temperatures, a cool and wet Pacific Northwest and warm and dry Southwest. The Late Holocene is the most variable interval, both spatially and temporally, and a novel spatial trend appears i
