In 1991 on the east side of the park were listed as a historic district on the National Register of Historic Places. Description The park contains more caves than any other state park in Iowa. A trail system links the caves, formations, and overlooks while providing a scenic hiking experience. Many areas on these trails have seen new construction, making the journey to the caves safer. Most of the caves may be entered by persons of average physical ability, but some are more advanced. However the park's caves were closed to humans between 2010 and April 2012 in the hopes of protecting the resident bats from white nose syndrome. The park is in the Driftless Area of Iowa. This region escaped being glaciated in the last ice age, while regions to the east and west were not spared. The park has been subjected to hundreds of thousands of years o ...

Geologic Timescale
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define gl ...

Rescue 911
''Rescue 911'' is an American informational docudrama television series that premiered on CBS on April 18, 1989, and ended on August 27, 1996. The series was hosted by William Shatner and featured reenactments (and occasionally real footage) of emergencies that often involved calls to 911. Though never intended as a teaching tool, various viewers used the knowledge they obtained watching the show. Two specials, titled "100 Lives Saved" and "200 Lives Saved," were dedicated to these viewers who had written to CBS with their stories on how the knowledge they obtained watching the show allowed them to save the life of someone else. At least 350 lives have been saved as a result of what viewers learned from watching it. The show's popularity coincided with the widespread adoption of the 911 emergency system, replacing standalone police and fire numbers that would vary from municipality to municipality. The number is now universally understood in the United States and Canada to be the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contributing Properties
In the law regulating historic districts in the United States, a contributing property or contributing resource is any building, object, or structure which adds to the historical integrity or architectural qualities that make the historic district significant. Government agencies, at the state, national, and local level in the United States, have differing definitions of what constitutes a contributing property but there are common characteristics. Local laws often regulate the changes that can be made to contributing structures within designated historic districts. The first local ordinances dealing with the alteration of buildings within historic districts was passed in Charleston, South Carolina in 1931. Properties within a historic district fall into one of two types of property: contributing and non-contributing. A contributing property, such as a 19th-century mansion, helps make a historic district historic, while a non-contributing property, such as a modern medical clinic, ...

Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Works Progress Administration
The Works Progress Administration (WPA; renamed in 1939 as the Work Projects Administration) was an American New Deal agency that employed millions of jobseekers (mostly men who were not formally educated) to carry out public works projects, including the construction of public buildings and roads. It was set up on May 6, 1935, by presidential order, as a key part of the Second New Deal. The WPA's first appropriation in 1935 was $4.9 billion (about $15 per person in the U.S., around 6.7 percent of the 1935 GDP). Headed by Harry Hopkins, the WPA supplied paid jobs to the unemployed during the Great Depression in the United States, while building up the public infrastructure of the US, such as parks, schools, and roads. Most of the jobs were in construction, building more than 620,000 miles (1,000,000 km) of streets and over 10,000 bridges, in addition to many airports and much housing. The largest single project of the WPA was the Tennessee Valley Authority. At its peak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
