 VALLEY DESCRIPTION Stream-cut. Not heavily wooded in its lower reaches. Valley is steep-sided 



on the N. side near its upper end. Mountainous terrain. 

 DRAINAGE 27 square miles (polar plonimeter). Precipitation fed. Large snowfields near the headwaters 



contribute small snowmelt at certain times of the year. Numerous feeder streams. 

 STREAM MOUTH IDENTIFICATION An extensive tideflat is found at the mouth. When the tide 



is out, the main cliannel flows in behind the outermost wooded island. 

 ANCHORAGE Good anchorage on the E. side of the small island and S. of the stream mouth. The 



channel is said to be clean. 

 TRAILS AND SURVEY ROUTES Boats should be left on the S. side of the creek at low tide. Bear 



trails follow the right bank up to forks; this bank is the most easily traveled. 

 AERIAL SURVEY NOTES A fair stream for aerial survey. Survey during low water because tlie water 



becomes dark during rainy periods.
