Photo 5.1-Photograph showing a natural arch of gypsum in the Gypsum Mountain area.<br />
as "Gypsum Mountain", covers an area of about 10 km 2 . An interesting weath<br />
ering feature is the occurrence of a series of natural arches, 18.5 m or more<br />
across, that have formed by solutioning along two watercourses that transect<br />
the area in north-south <strong>and</strong> east-west directions (Photo 5.1). Gypsum Mountain<br />
represents the peak elevation of the gypsum sequence above sea level.<br />
FRENCH RIVER<br />
Several small outcrops of gypsum occur over a distance of 0.4 km on the<br />
east bank of the Wakwayowkastic <strong>River</strong>, central branch of the French <strong>River</strong>.<br />
The outcroppings expose a 2 to 3 m section of good quality white, finely granu<br />
lar, massive gypsum with traces of grey-black, crenulated, limestone laminae.(Guillet<br />
1967).<br />
