This study investigated the physical (particle size and shape, particle density, bulk density and porosity) chemical (mineralogy and elemental composition) and hydrologic (water retention, hydraulic conductivity, and sorptivity) characteristics of laboratory and wildfire ash from the Northern Rocky Mountain region of the United States. A variety of techniques were used including scanning electron microscope, X-ray diffraction, thermogravimetric analysis, and conventional soil science techniques. Results of this study indicate that variation in the hydrological response of ash can be partially explained by differences in ash characteristics associated with combustion temperature. Furthermore while ash color is often used as an indicator of burn severity it may not be an accurate indicator regarding the hydrologic response of ash in post-fire systems. Instead carbonate content is suggested as a more informative aid in predicting post-fire hydrologic response
