When many local historians first considered how the hill was created,
many supposed that this was a man-made mound. But, as it was
investigated more thoroughly, it was revealed to be a glacial mound.
That is - as the glaciers receded from this area, boulders, silt, mud,
and rock were dragged and dropped in our valley. Now there are a couple
of theories on how Spanish Hill was created because of this, but it is
accepted that given whatever the process, Spanish Hill is made up of
glacial deposits, and was not man-made.
most accepted theory is that the height of the land in this area was the
height of Spanish Hill at one time long ago. And with the great
flooding and receding of the glaciers, the area around the hill loosened
and was washed away. This left an "island" in the great flooding, but
when the water receded, left this great rise of land with the flat top,
which we now call Spanish Hill. Click

is said that when they put in the highways that they were going to
remove the hill and use the soil to build up for the highways...But
Cowles went to Harrisburg to save the hill. In the
end, only the east side was "cut" to make way for Rte. 220. But in
doing this, it revealed the makeup of the hill. This finally ended all
questions of whether or not is was man-made. (If anyone has any of those
photos - I would really love to have some to post to this website.)
