It should not be confused with a similarly named stream that runs through Fourmile Canyon west of Boulder, which was the site of a major wildfire in 2010. This stream rises west of the old mining settlement of Sunshine. It runs eastward through the foothills of the Front Range in Boulder County, Colorado, south of Left Hand Canyon and north of Sunshine Canyon. The creek exits the mountains to the plains near Lee Hill Road in northern Boulder, then flows east an additional through the plains to its confluence with Boulder Creek near Valmont.

Flash Flood
A flash flood is a rapid flooding of low-lying areas: washes, rivers, dry lakes and depressions. It may be caused by heavy rain associated with a severe thunderstorm, hurricane, or tropical storm, or by meltwater from ice or snow flowing over ice sheets or snowfields. Flash floods may also occur after the collapse of a natural ice or debris dam, or a human structure such as a man-made dam, as occurred before the Johnstown Flood of 1889. Flash floods are distinguished from regular floods by having a timescale of fewer than six hours between rainfall and the onset of flooding. Flash floods are a significant hazard, causing more fatalities in the U.S. in an average year than lightning, tornadoes, or hurricanes. Flash floods can also deposit large quantities of sediments on floodplains and can be destructive of vegetation cover not adapted to frequent flood conditions. Causes Flash floods most often occur in dry areas that have recently received precipitation, but they may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trailhead
A trailhead is the point at which a trail begins, where the trail is often intended for hiking, biking, horseback riding, or off-road vehicles. Modern trailheads often contain rest rooms, maps, sign posts and distribution centers for informational brochures about the trail and its features, and parking areas for vehicles and trailers. The United States Access Board states "A trailhead is defined as an outdoor space that is designated by an entity responsible for administering or maintaining a trail to serve as an access point to the trail." The intersection of two trails is a trail junction and does not constitute a trailhead. Historically, the cities located at the terminus of major pathways for foot traffic such as the Natchez Trace and the Chisholm Trail were also known as trailheads. For mountain climbing and hiking, the elevation of the trailhead above sea level is posted to give an idea of how high the mountain is above the Height above average terrain, average terrain. ...

Sunshine Canyon
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When blocked by clouds or reflected off other objects, sunlight is diffused. Sources estimate a global average of between 164 watts to 340 watts per square meter over a 24-hour day; this figure is estimated by NASA to be about a quarter of Earth's average total solar irradiance. The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a requisite for vitamin D3 synthesis and a mutagen. Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the center of the Sun and changing direction every ...
