Show ( Masai' Masai Misex ) ( page 61 , Exhibit ( 108 US ) 56 ) : ( Much Afuch ) of the sand that is present ( along a'loiig aloiig ) the river is being continually moved ( down- down ) ( stream streani ) . It is piled up in shifting ripple and ( rill-marked rillmarked ) bars . Some of the bars are ( ex- ex ) posed as ( small saiall ) and large areas adjacent to the river , and ( some sonie ) rise above the water as islands , but others are ( submerged subinerged ) for ( depths deptlis ) ranging from a ( small sniall ) ( fraction frdction ) of an ( inch hich ) to perhaps ( many inany ) feet . Sand underlies ( the tlie ) bed of the river for long distances . For ( example exan-iple exaniple ) , Loper and ( I 1 ) , in towing a boat upstream from the mouth of Piute Creek to Spencer Camp , a distance of 16 miles , waded the river ( with -with with ) bare feet the entire distance and ( encountered encouutered ) gravel and boulders at only two or three places ; only a few shoals were so deep that they could not be ( vaded waded ) . The sand , on account of its fine grain , is generally firm and compact enough for a person to ( walk vulk ) ( 011 on ) its surface ; though in ( do- do ) ( ing ilig ) so he causes wavelike movements in the sand around ( him hh-n hhn ) and is ( likely lilk-ely lilkely ) to ( sink sinl- sinl ) into it if he retraces his steps . Quicksand is usually confined to the lower ends of the sand bars where it is being piled continually by the river and where it has not yet had time to become compact The deepest quicksand encountered by members of the party was not more than waist deep .
