Atlin Lake. 



Atlin Lake, altitude 2,220 feet, is a large body of snow and glacial water, almost one 

 hundred miles in length and averaging about five miles in width. The lake is very deep in 

 spots ; in fact, in some places the depth is unknown. The shore-line is indented with many 

 bays, a number of points, and dotted with many islands of various sizes. Teresa Island, 

 locally called " Goat Island," is the largest on the lake. It is, roughly speaking, about sixteen 

 miles long and five miles wide across the centre. The highest snow-peak on this island is 

 3,480 feet above the lake. Fishing on the lake is very good ; Arctic grayling and the char, 

 or Great Lake trout, are very plentiful. Whitefish are also plentiful. Perhaps the most 

 remarkable sight is the " Llewellyn Glacier." This enormous field of ice stretches from the 

 southern end of Atlin Lake to the "Taku Inlet," on the coast, covering an area approximately 

 ninety miles long, many parts of which reach thirty miles in width. I had the pleasure of 

 viewing both bases ; the size is beyond apprehension. 



Pike River. 



Pike River is about twelve miles long, flowing north-west and emptying into Atlin Lake. 

 We camped at an abandoned telegraph-station about half a mile from the mouth and sheltered 

 in a secluded bay. Most of the surrounding country is flat, with a few small lakes, and 

 timbered with willow, poplar, cottonwood, and spruce. Near the mouth of the river grayling 

 are plentiful. Work was carried on here from July 25th to August 8th, three days of which 

 we collected at Anderson Bay, about four miles distant by water from the Telegraph Cabin. 

 The small inland lakes near Moose River revealed some desirable specimens of birds and 

 mammals. The mountains were explored, but produced nothing of importance, save recording 

 two nests of Golden eagles. The Pika Slide was searched, but none were taken. In all 

 probability they were buried under a snowslide which occurred the day previous to our visit. 



Hot Springs. 



The country is wooded with spruce and pine, and considerable willow and cottonwood in 

 the bottom lands. Several small lakes are to be found close to the base of a range of mountains 

 running north and south. The Hot Springs are located about a third of a mile from Warm 

 Bay, Atlin Lake, where Mr. Joe Housel nas erected a bath-house which is used to good 

 advantage by passers-by. We camped on the shores of Atlin Lake from July 1st to 28th, 

 moving by boat to Pike River. 



Wilson Creek. 



A fork of O'Donnell River, about eight miles long. The country on both sides is moun- 

 tainous, excepting the head, where open willow-brush is found on the higher elevations. Willow 

 ptarmigan are found commonly on the table-lands during the summer, breeding in suitable 

 places, usually near water. We camped at the base of Gopher Dam Mountain, close to a small 

 lake ; and collected in the surrounding district from June 7th to July 1st, securing many 

 valuable specimens. 



BIRDS COLLECTED AND OBSERVED IN THE ATLIN DISTRICT, 1911. 



Holbosl's Grebe {Colymbus holbmllii, Bernhardt). 



On Jul}' 12th a pair with five downy young were observed close to the lake-shore at 

 Warm Bay. Three were seen at Surprise Lake on August 16th. Although we collected at 

 several small lakes, etc., the birds were found scarce during the nesting season. It is a 

 common bird during the month of September on Lake Atlin. 



Horned Grebe (Colymbus auritus, Linnaeus). 



A single bird was seen on a small lake at Atlin on August 15th. It was common at 

 Atlin Lake in September, 1913. 



Loon, Great Northern Diver (Gavia immer, Brunnich). 



A few birds frequented Warm Bay, Atlin Lake, during July. Several were seen near 

 Pike River early in August.
