Journal R.E. Johnson 1967 August 27 Helena to Big Baldy Mtn, Little Belt Mtms, Judith Basin Coy, Montana. so steep as the second (northern) cirque. There are some near vertical cliffs facing north above Rhoda Lake but otherwise the slopes are very steep rock slides. The northern cirque is also very alpine & has very large cliffs on the sw corner (ne facing) with a very large snow pack below. Their cirque is subdivided into 3 parts & has two lakes [Twin Lakes (8015 & 7870 ft)] below. The central (main) cirque is the most likely meeting site for Rosy Finches. Water Pipits were very common, apparently in family groups, along the top & they fled to cover inside the lip of the cirques when the wind periodically blew from the sw. [Thunderstorms continually passed over from 3-8 PM]. A Water Pipit and a Sprague's Pipit (Imma) were collected on Big Baldy Mtn. This is the first record for a Sprague's Pipit above the foothills of the range. (see Hoffmann, 1960 - Summer Birds of the Little Belt Mtms, Montana). Perhaps these moved up after breeding was past. Only one group of 5 or 6 were noted. Hoffmann notes that pipits [water] are common on Yogo Pk but less common on Big Baldy. This conforms to my observations for the summer of 1964 (see Johnson, 1966 - Wilson Bull. 78: 225-227) when they nested in great densities on Yogo Pk. However this fall Water Pipits are very common on Big Baldy. My only previous visit to Big Baldy was in early August 1964 & Hoffmann's last visit to these mtms was Aug. 20 (but he perhaps didn't visit Big Baldy Mtn this late), so perhaps Water Pipits move to Big Baldy in the fall. A Horned Lark was also collected. Several Say's Phoebe were seen and one was collected along the cirque top. This is the 1st record for this species within these mtms, although it
