Show on J JC C GEOLOGICAL CLU CLUB The Geological al Club Club took a trip to the j Little Cotton Cottonwood wool wool-on on Saturday March 12 The club left Salt Lake City at 8 4 a. a m. m J on the Murray car and wa was met at Murray by a horse four-horse carriage carriage h with with Escorted by a t troop of horse and an accompaniment of music the club left the city Considering the fact that tha there were thirteen in the wagon th the the could not breaking of a seat on way be counted as serious serious approached th the As the Wasatch was north remnant remnant of the gr great at an anticline I I whose south end is at Provo Prove was was- observed Approaching nearer numerous nu nu- fault scarps were seen five parallel parallel parallel par par- scarps being counted at one point These scarps are among the freshest of those of the great Wasatch system and anda a little further on where the road passes through a trench in the north moraine of the Little Cottonwood they are so fresh that at the upper courses they are not yet covered with vegetation and in places are too steep to be clim climbed bed This trench in the moraine has been caused by parallel parallel parallel par par- faults the block between having been dropped down On the side nearest nearest nearest near near- est the mountain the scarp is from 40 to 60 feet high The scarp here exposes the characteristic character character- material of the moraine fragments of all sizes mixed with fine material into a heterogeneous mass entirely unsorted and Huge boulders are conta contained contained con con- ta ned in it and far up on the mountainside mountain mountain- side more than feet above the moraine are scattered boulders of granite granite granite gran gran- ite showing the height which the glacier once reached The walls of the canyon at its mouth are of dark quartzite but further up they are of white granite and the glacial drift being nearly all appears very prominent against the dark background The n north rth moraine is broad and flat rising only about feet above the flood plain of the creek and is not of typical form It appears s since since nce granite boulders extend along the side mountain-side f for half a mile beyond the canyon that after the Uie glacier had formed the two moraines in the usual way it expanded toward the north overthrowing the moraine oraine on that hat side The south moraine raine is of the usual form Where it Joins the mountain it stands 3 0 feet above the flood plain of the creek Its f formation and extent was not examined but bt the faul fault a scarp continuing up anci and ond it was clearly seen Further urther up the canyon the line of con con con- tact b between tween the dark quartzite and the 4 k 1 white granite was observed and the t J great joints in the granite showed as unbroken unbroken un- un I broken lines extending from top to bottom bot- bot 1 r tom torn of the canyon canyon A beautiful exam example example le of stream erosion was at fJ seen a point ii fJ where the Little Cottonwood flowing ff over a solid granite flat had cut it into smooth rounded wave-like wave forms On the return the power house in Big t Cottonwood was visited and through the Jf v kind kindness ess of the engineer Mr Scales the f j workings of the dynamos were explained d and one of the extra engines started up for our special bene benefit fi t. t i The club returned to Salt Lake City at o'clock in the evening and though some of the members had haa sunburned sunburned sun sun- J burned faces yet all pronounced the day daya a jolly one well spent t. t i |
