  • Doing Niagara Falls If You're Stuck on the American Side
    Meiqianbao/ Shutterstock Doing Niagara Falls If You're Stuck on the American Side By Jason Cochran The legendary Niagara Falls, one of the greatest natural attractions in North America, straddles the border between Ontario, Canada, and New York State. In an ideal tourism situation, you'd be able to drive or stroll across the Rainbow International Bridge to enjoy the view from both banks of the Niagara River. But sometimes you just can't get over the border. Maybe you don't have enough time. Maybe your legal status won't allow it. Or maybe you happen to be living through a once-in-a-lifetime global pandemic that has sealed national borders. It's all good! If you're restricted to the U.S. side, you won't find yourself over a barrel. There's plenty to do. In fact, some of the best activities in the Niagara Falls area are on the American side. Pictured above: Terrapin Point, at right, juts into the eastern side of the Falls from Niagara Falls State Park in New York State. Niagara Falls State Park Niagara Falls State Park If we're being honest, the Canadian side has richer options for quality lodging and tourist amenities, although the stuff on that riverbank tends toward cheesy honky-tonk. New York's territory beside the Falls, on the other hand, has been preserved from development since the 1880s. In fact, the area is now the oldest state park in the United States. The more-than-400-acre Niagara Falls State Park, which is separated from the core of town by a breakaway river, is speckled with whitewater-spanning bridges, river islands, curving walkways, and native animals.

  • Downtown Neighborhood City of Niagara Falls: Phase I
    Intensive Level Survey Historic Resources – Downtown Neighborhood City of Niagara Falls: Phase I 3.0 Historical Overview This section provides a narrative history of the City of Niagara Falls with specific emphasis on the Downtown neighborhood. The overview addresses significant trends and themes associated with the city’s historic context. The Downtown neighborhood’s period of significance is identified and examined in this chapter. Martin Wachadlo, architectural historian, conducted the background historic research. 3.1 Niagara County: Physiology and Geology Figure 3-1. Niagara Falls, Niagara Falls, New York Niagara County borders the southern shore of Lake Ontario in the extreme northwestern corner of New York State, and occupies part of the Huron and Ontario Plains. The Ontario Plain comprises part of Lake Ontario to the foot of the Niagara Escarpment1, and the Huron plain extends from the crest of the escarpment southward beyond the county line. The Niagara Escarpment begins in Watertown, New York, USA and extends westerly along the Manitoulin Island in the Province of Ontario, Canada. The escarpment continues through Wisconsin and Illinois. With geological material measuring 64-ft thick, the stratigraphy at Niagara Falls provides a glimpse into the overall rock types comprising the Niagara Escarpment (Figure 3-1). The top layer is Lockport Dolomite, a hard rock referred to as the "Lower Silurian Group." Below the top layer is Rochester Shale, which is much softer and wears away easily with the effects of erosion. Under the shale are harder strata of limestone and dolostone known as the "Clinton Group." Below the harder strata is Grimsby sandstone.

It is divided into two distinct falls known as th<5 American and Horseshoe Falls, by Goat Island, which is now a gov- ernment reservation. The American Fall is 1 67 feet high, 1 060 feet wide. Horseshoe Fall is 158 feet high and 3010 feet wide. It is estimated that 1 5,000,000 cubic feet of water pass over both falls each minute. The total fall of the Niagara River, from its source at Lake Erie to Lake Ontario is 336 feet, as follows: From Lake Erie to the brink of the faUs, 70 feet, at the falls. 161 feet, from the falls to Lake Ontario 105 feet.

  • Botanical Evaluation of the Goat Island Complex, Niagara Falls, New York P
    BOTANICAL EVALUATION OF THE GOAT ISLAND COMPLEX, NIAGARA FALLS, NEW YORK P. M. Eckel Buffalo Museum of Science 1020 Humboldt Pkwy Buffalo, NY 14211 U.S.A. www.buffalomuseumofscience.org Return to Table of Contents ORIGINS OF THE FLORA The flora of the Goat Island complex and the Niagara River Gorge represent a floristic anomaly within the characteristic regional vegetation of the Niagara Frontier. This is based on the high species diversity and abundance reported for the area of the falls. All vegetation in the area has been reintroduced since the last glacial period. All species became established through opportunities provided by regional and local climatic regimes, substrates, water levels, topographic variation and natural disturbance regimes within the study area favoring the establishment of a diversity of habitats supporting species with a wide assortment of different tolerances and competitive advantages. The Niagara Reservation consists of the margin of a river and a series of islands. These two conditions alone serve to distinguish these natural areas ecologically from those of the surrounding continuous landscape. The original forest, depicted in nineteenth century and earlier pre-photographic engravings and illustrations as growing down to the river and gorge edge, would have had a boundary there. So, too, would its darkening canopy and the modification of environmental conditions within it. Life on the margin would be exposed to sunlight, to weather, to soil changes, soil textures with different nutrients, and to increases in soil moisture and the mechanical effects of the same moisture freezing in winter, fluctuations in water levels, etc. These different physical conditions would have and do create opportunities for distinctive plant communities, with species assemblages differing from those of the forest dominating the enclosing region.

  • Final AESE 2018 Meeting Information
    Association of Earth Science Editors 52nd Annual Meeting Niagara Falls, New York, September 26 to 29, 2018 (3rd and Final Meeting Circular – August 2018) The Association of Earth Science Editors’ next annual meeting—its 52nd—will be held in Niagara Falls, New York, September 26 to 29, 2018. We hope you’ll join us for what promises to a great meeting, in a spectacular setting. AESE meetings are a wonderful way to learn about earth science editing, publishing and communication. Meetings are generally small in size and provide unparalleled opportunities to network with other editors, publishers and educators working in the earth sciences. This year’s Technical Program Chair is Phil Farquharson (San Diego Miramar College), and Host Chair is Marg Rutka (Ontario Geological Survey). We’re looking for volunteers, so if you would like to help out with planning the meeting or have ideas about talks, what we should see on the field trip, and speakers we could approach for the technical sessions or the Awards dinner, please get in touch with Phil or Marg (contact information at the bottom of this document).
