To Start:First you must find the Saguaro day use lot,from there you will find your mark.Take the way towards the Siphon Draw trailif you do not start here the whole hike will fail.Food for Thought:Take a minute to look around and observe the majesty and grandeur of the mountain. If you have arrived here just after a rainstorm then you will also notice just how green the desert has the potential to be. First Stop:The memorial bridge is the first stop on the quest,find it but there's no time to rest!Continue around the bend,and later you may just get to the end.Food for Thought:Although the creek the bridge runs over is dry for most of the year when the desert floods it runs with the life giving water that sustains all life on Earth. Second Stop(s):Away from the bridge and down the path you'll notice animal plaques on the ground,look at the many different animals you've found!To the right of the path they sit,But you've got to continue on, this is no time to quit.Food for Thought:All these plaques depict a different animal indigenous to the Sonoran desert. See how many of them you can stop as you continue on your hike! Third Stop:Look to the left, look to the right,this next stop might give you a fright!Off to the trail to the left is something dark,On this desert, the coyote has left its mark.Food for Thought:Coyotes are one of the most famous of desert carnivores. Although mostly considered pests, coyotes are beneficial to desert ecosystems because they keep populations of other species in check. Fourth Stop:Continuing down the trail this next stop might be easy to miss,But trust me, you don't want to go by this.To the left of the trail you'll find some ancient Indian ruins,For this stop you'll definitely want to clue-in.Food for Thought:Long before European settlers reached the Americas, indigenous peoples lived here. The ancient Hohokam tribe, who inhabited the Valley of the Sun thousands of years ago, probably left these ruins. Fifth Stop:Now for a little time to rest,this next spot really is the best.These two gigantic boulders provide excellent shade,Take this time to eat that snack you made!Food for Thought:Rest is important during prolonged physical activity. These two gigantic rocks provide an excellent place to sit and rest. See if you can take this time to spot any desert fauna or organisms you may know. Sixth Stop:And now we start up the mountain face,take it easy and go at a comfortable pace.Up the trail a ways is a small natural spring,don't drink from it though, you don't know what it could bring.Food for Thought:Natural springs provide an excellent source of water for the desert. In some parts of the desert the easiest way for plants and animals to get water comes from underground sources. Although animals drink from these pools it probably isn't safe for human consumption because of the impurities. Seventh Stop:The next stop up the mountain is something very cool,wouldn't you know it, it's a cesspool!It's a nice place to stop and sit,but I still wouldn't drink from it!Food for Thought:Although the water in this cesspool is filthy it still contains an incredible, microscopic ecosystem. The germs that make us sick are contained in the pool, thriving in the stagnant water. Last Stop:This is the last stop on our trip,this high up you won't want to tip.Look up at the mountainside,a waterfall runs down in unless it has dried.Food for Thought:This is something that most people never expect to see in the Arizona desert. This waterfall probably took millions of years to form from the erosion that took place as uncountable gallons of water flowed down from the mountain after a storm.
