![]() While not all of Washington's waterfalls are easy to access, many can be reached by hiking or backpacking. Washington has over 3,000 documented waterfalls, the majority of which are located in the western half of the state. What are the tallest waterfalls in Washington? Bridal Veil Falls, Pikes Peak State Park. ![]() Palouse Falls, Palouse Falls State Park.During particularly cold years, here are just a few possible frozen waterfalls in Washington: While winter temperatures in Washington vary from year to year, there are a few waterfalls that are known to freeze regularly. What are some must-see frozen winter waterfalls in Washington? Mazama Ridge, Mount Rainier National Park.Crab Creek Wildlife Area, Columbia National Wildlife Refuge.Thunder Creek, North Cascades National Park. ![]() Wikipedia Frozen waterfalls at N China's Taihang Mountains attract tourists CGTN 3.02M subscribers Subscribe 9.6K. Winters in Washington state are known to be cold, wet, and overcast, but don't let that stop you from exploring! There are plenty of beautiful winter hikes and hiking areas in Washington that are worth the extra effort, layers, and planning: 0:00 / 0:26 CGTN is funded in whole or in part by the Chinese government. 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.Where can I hike in winter in Washington? 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. A tourist views the frozen waterfall in Mimishui scenic spot in Pingshan County of Shijiazhuang, capital of north Chinas Hebei Province, Dec. Tourists take selfie in front of the frozen waterfall in Mimishui scenic spot in Pingshan County of Shijiazhuang, capital of north China's Hebei Province, Dec. 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. Aba, China Huanglong Terraces (photograph by chensiyuan/Wikimedia ) Known as the dragon for their winding shape, the Huanglong Travertine Terraces in southern China flow for 2.2 miles. 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.
