Nicole Mansfiield suits up for the 30 foot Medina waterfall in Medina NY. This creek runs under the Erie Canal just before turning and falling about 30 feet. Â So yes, essentially there is a river running over another river (canal) a little different to say the least. Â The Erie Canal dumps water into the creek right above the waterfall making this park and huck runnable most days of the year! Â Here is a video of Nicole sending this drop! Â Click Here!
