Introduction to Nitrate Waterfall: Nitrate Red Cliff is steep and majestic. The silver mountain spring rushes down from the peak more than 80 meters high. The water mist drifts in the wind, like a "white snake" descending. It is extremely beautiful. On the left side of the waterfall, there is a rock crevice with a height of 4 to 6 meters, a width of 3 to 8 meters, and a length of more than 300 meters. After natural weathering, the rock oozes out a kind of crystalline substance of nitrate, which is exposed under the sunlight. It is like frost and dew, slightly shining, dazzling, magical and wonderful, hence the name of saltpeter.
