Additionally, the park is free of charge and filled with several limestone bluffs and river overlooks that are also worth seeing while blanketed with snow.

This waterfall regularly freezes in the winter and because it’s smaller, visitors can walk underneath it, allowing them to experience a frozen waterfall up close.

Since the placement of the bridge is a little lower, it allows onlookers to gaze up at the optically giant waterfall, completely suspended.Īlthough much smaller at a mere 53 feet tall, the Minnehaha Falls in Minnesota is located at the center point of the Minnehaha Regional Park. And the view is perfectly situated from the pedestrian bridge which is located above the lower fall and eye-level with the base of the upper fall. Even when it’s not completely frozen, unfrozen water running across the bright translucent blocks of ice can look stunning in the winter sun. Although these falls are very large, they are capable of fully turning to ice once the temperature drops below freezing. Located along the Columbia River Gorge Highway, the Multnomah Falls cascade 620 feet down a cliffside. Here are some winter waterfalls across the United States that are so beautiful they’ll leave you frozen. And, if we can even see the beauty in the ice crystals hanging off of our homes, imagine the majesty of a giant frozen waterfall. They look hard and still in the winter cold and then, when the sun peaks out, they transform what appeared to be a dark winter landscape into a bright sparkling natural wonder. Ice fixtures, for example, form naturally and come in every shape and size you could imagine. Nevertheless, the algorithm has limited capability in identifying the soil surface freeze/thaw state in the arid region, because the microwave signals can penetrate deep dry soils and thus embody the bulk information beyond the surface layer.Some of the most inspirational views are those that nature creates all by itself. Results show that the classification accuracy using this algorithm is more than 90% for the semi-humid and semi-arid regions, and misclassifications mainly occur at the transition period between unfrozen and frozen seasons. Further validations were conducted based on the other two networks located in different climates (semi-humid and arid, respectively). The threshold values of the two indices (SDI and ) are determined with one grid from the network located in a semi-arid climate, and the algorithm was validated with other grids from the same network. The other index is the 36.5 GHz vertically-polarized brightness temperature ( ), which is linearly correlated with ground temperature.

It is the major index, and is used to reflect the reduction of liquid water content after soils get frozen. One index is the standard deviation index (SDI) of brightness temperature (TB), which is defined as the standard deviation of horizontally polarized brightness temperatures at 6.9, 10.7, 18.7, 23.8, 36.5 and 89.0 GHz. With the support of three soil moisture and temperature networks in the Tibetan Plateau, a dual-index microwave algorithm with AMSR-E (Advanced Microwave Scanning Radiometer-Earth Observing System) data is developed for the detection of soil surface freeze/thaw state. The land surface on the Tibetan Plateau experiences diurnal and seasonal freeze/thaw processes that play important roles in the regional water and energy exchanges, and passive microwave satellites provide opportunities to detect the soil state for this region. This paper provides an overview of recent achievements, challenges, and opportunities for land remote sensing of cold regions by (a) summarizing the physical principles and methods in remote sensing of selected key variables related to ice, snow, permafrost, water bodies, and vegetation (b) highlighting recent environmental nonstationarity occurring in the Arctic, Tibetan Plateau, and Antarctica as detected from satellite observations (c) discussing the limits of available remote sensing data and approaches for regional monitoring and (d) exploring new opportunities from next-generation satellite missions and emerging methods for accurate, timely, and multi-scale mapping of cold regions. With the advance of earth observation technology, remote sensing has become increasingly important for detecting, monitoring, and understanding environmental changes over vast and remote regions. Cold regions, including high-latitude and high-altitude landscapes, are experiencing profound environmental changes driven by global warming.
