I'm having issues determining the slope of my raster created from a GA layer. I've searched around on the forums and made sure that my coordinate systems are all the same and are projected coordinate systems for my region. My rasters seem to be accurate, but when I use the slope tool in spatial analyst I am getting results that are very steep, most of the slope raster has a nearly 90 degree angle. I attached a screen capture of my results. I have tried to calculate the slope from many different interpolation techniques (IDW, LPI, RBF, Kriging) and always seem to get this output.
