Headwater streams (HWS) are ecologically important components of montane ecosystems. However. they are difficult to map and may not be accurately represented in existing spatial datasets. We used topographically resolved climatic water balance data and satellite indices retrieved from Google Earth Engine to model the occurrence (presence or absence) of HWS across Northwest Montana. https://lecoureures.shop/product-category/course-a-pied-homme-vetements-manteau-duvet/
