Communication of information between neurons is accomplished by movement of chemicals across a small gap called the synapse. Chemicals, called neurotransmitters, are released from one neuron at the presynaptic nerve terminal.
Follow Trail 12 until it runs back into trail 1 and familiar sights and then you are only about 200 yards from the great Cumberland Falls. To the best of my guessing ability I would say this loop was about 8.5 miles long which took us about 3 hours and 45 minutes.
Fed by underground springs from Larch Mountain, the flow over the falls varies usually being highest during winter and spring. Multnomah Falls offers one of the best places in the Columbia River Gorge National Scenic Area to study geology exposed by floods. Five flows of Yakima basalt are visible in the fall's cliff face. From the information center, visitors can follow the 2.4 mile (RT) trail that climbs approximately 600 feet to the top of Multnomah Falls. This trails provides great views of the falls and the Columbia River Gorge. Once at the top of the falls, hikers can continue onward for six miles to the top of Larch Mountain or take the six mile Wahkeena Loop trail.
