Shorts Creek begins its journey west of Terrace Mountain. It makes its way down to the delta, forming three cataracts within Fintry Park. The first is fairly sedate, the second is more enthusiastic and the third, closest to the delta, is spectacular. The falls have eroded through granite. This erosion started during the post-glaciation period about 11,000 years ago. Similar erosion formed the canyons around KLO Creek, BX Creek, Bellevue Creek, Deep Creek, and Trout Creek.
The sediment, mostly sand and gravel, which was carried by Shorts Creek until it reached Okanagan Lake, was deposited forming the delta. The delta is between 2 and 6 meters above the current level of the lake, which indicates that it was first formed when the lake level was that much higher than it is today.

<1) Estimate the height of the lowest of the three falls. 2) Estimate the volume of the concrete structure behind you as you face the falls at GZ.3) Is it reasonable to assume that this container is a water reservoir to be used during low-flow months?
