![]() The Harlequin campground is located next to the airport. The airport is often a base for firefighting, at which times it is closed to public use. While only 1,230 ft (370 m) msl, there are mountains on the sides and trees at each end of the 2,630 ft (800 m) runway. The airport is only open July, August, and September, and is noted by the Washington State Department of Transportation as being one of the state's most challenging airports. In addition to access by Lake Chelan, visitors come to Stehekin by horseback, hiking, and flying into Stehekin State Airport (Identifier 6S9). The vehicles in Stehekin have been barged there on Lake Chelan. It is reachable by passenger ferry (the Lady of the Lake), by private boat from Chelan, by foot over Cascade Pass, by floatplane, or by small aircraft via a turf airstrip open from June through September. There is no road access to Stehekin, although roughly 22 miles (35 km) of road exist there. Stehekin is visited by hikers and bikers in the summer, and snowshoers and skiers in the winter, as well as photographers year-round. Sights in Stehekin include the Buckner Homestead Historic District, The Golden West Visitor Center, Stehekin Pastry Company, the one-room Stehekin School, the 312' Rainbow Falls, and Harlequin Bridge. ![]() Stehekin is within Lake Chelan National Recreation Area, a unit administered by the National Park Service. Located at the northwest end of Lake Chelan, it lies just south of the North Cascades National Park. Stehekin is part of Wenatchee– East Wenatchee Metropolitan Statistical Area. Stehekin has about 75 permanent residents, although its population swells during the summer with vacationers and seasonal workers. The name "Stehekin" comes from a word in the Salishan language that means "the way through".

Learn more about these spring maps in our AGDD and Spring Indices info sheet. We determine how often a spring was at least this early (or late) by taking the number of years in the record divided by the count of years that were earlier (or later) than the current year. To calculate how often we see a spring as early or late as the current spring, we compare the current year's Spring Index Anomaly value to the anomaly values from the previous decades. Climate Central offers more detail about how seasonal average temperatures have shifted from the prior to the current climate normal period. In 2022, we updated the period of comparison for our spring leaf out and bloom anomaly maps to the new climate normal of 1991-2020, following standards set by NOAA and the World Meteorological Organization. Long-term averages were calculated using PRISM Climate Data daily minimum/maximum temperature data (Oregon State University). To determine how the current spring compares to “normal”, we difference the day of year the leaf out or bloom was reached this year from the long-term average (1991-2020) day of year it was met. More information is provided in our Gridded Product Documentation. Maps for the current year are generated using temperature products from NOAA National Centers for Environmental Prediction Real-Time Mesoscale Analysis. Primary inputs to the model are temperature and weather events, beginning January 1 of each year (Ault et al. These species were selected because they are among the first woody plants to leaf out and bloom in the springtime and are common across much of the country. x chinensis 'Red Rothomagensis') and two cloned honeysuckle cultivars ( Lonicera tatarica 'Arnold Red' and L. These models were constructed using historical ground-baesd observations of the timing of first leaf and first bloom in a cloned lilac cultivar ( S. The Extended Spring Indices are mathematical models that predict the "start of spring" (timing of leaf out or bloom for species active in early spring) at a particular location (Schwartz 1997, Schwartz et al. USA-NPN also produces a suite of Accumulated Growing Degree Day map products.Īccess Phenology Maps What is behind these maps?
