Site S10. This site has many broken, extremely rugged cliffs for 
escape terrain. Vegetation is very plentiful and at close proximity to 
the cliffs. It is located on known winter range and the slope is 
extremely steep. Sites SlOa and SlOd face north and sites SlOb and SlOc 
face south west. 
Site Sll. This is a very small southwest-facing cliff that is not 
rugged nor is it on a steep slope. There is adequate vegetation and it 
is located at a ridgetop. 
Site S12. This site is a continuous sawtooth outcrop in the middle 
of a southwest slope that is fairly shallow. The cliff is rugged, but 
is not good escape terrain because of its continuity. Vegetation is 
plentiful: the outcrop is surrounded by well-vegetated slopes. 
Site S13. This rugged, broken outcrop is low in altitude and located 
on a shallow slope that faces southeast. Vegetation is plentiful, but 
the lack of protection from predators precludes its suitability for 
lambing. 
Site S14. This scattered group of low cliffs has a southeast aspect 
and adequate vegetation. The slope is very shallow and predators have 
easy access. 
Site S15. This area is similar to site S14, but faces northwest. 
Site S16. These isolated cliffs face south. The almost flat slope 
is lacking plentiful vegetation. 
Site S17. This open, shallow slope has a few broken cliffs. They 
are low in height and face south. Vegetation is adequate. 
Site S18. These jagged cliffs face southwest. The vegetation is dry 
but still suitable. The slope is very shallow. 
Site S19. The slope faces southwest, but the cliffs are on a knife- 
edge and face southeast (Site S19a) or northwest (Site S19b). It is 
very steep and vegetation appears adequate. 
Site S20. The site has four outcrops on a flat, southwest-facing 
slope. The cliffs are not very rugged, nor is the vegetation plentiful. 
South Ogilvie Mountains Summary 
Of the twenty sites analysed, only three (SI, S3 and S10) are clearly 
suitable for lambing. Sites SI and S10 are known to be used for 
lambing and, in all likelihood, ground truthing would show that S3 is 
used as well. However, the amount of protection and opportunities for 
isolation in sites SI and S10 greatly exceed that of all other sites. 
Vegetation is most abundant in these sites and provides the best forage. 
Sites S8 and S9 should also be investigated in the field. However, their 
limited ability to protect ewes and lambs is the greatest factor against 
their suitability. The remaining sites have one or more of the following 
undesirable characteristics: they are too low, too flat in terms of the 
slope on which the outcrops are situated, have no grazing areas, the 
cliffs are not rugged or broken enough, the aspect is such that it holds 
too much snow late into the spring or the site is not near winter range. 
This evaluation does not preclude the other sites from investigation. 
Rather it presents the investigator with a starting place of the most 
likely lambing areas. 
Central Ogilvie Mountains (s ee Photos 3 and 4) 
The central Ogilvie sheep range consists of habitat very different to 
that of the south Ogilvies. There are no large massifs with large cliff 
faces. Instead, cliffs often appear as outcrops on barren talus slopes. 
It is unknown where this sheep population winters: no areas were 
identified in previous studies (Stewart 1981).
