spatial analysis % slope calculation with odd values

Hi fellow GIS users:

I ran the spatial analysis slope calculation using a 2ft dem (va state plane projection in ft).  The projection of my map is in va state plane feet.  I ran the calculation for % slope with no z-factor (all units are in ft).  The resulting data has % slope values from 0-6,881.  These values seem odd to me- I would think the values should be from 0-90%? I'm wondering if others have run into this data problem and how to fix it?

Thank you,
Julie Schneider
