Aho ndoned Beaches of Lake Superior. — Taylor. 115 
recognized it became a valuable aid in identif_ying this beach 
at places wideh'^ separated. Its great strength, however, is 
the most reliable character for its recognition. Sometimes 
this quality may not appear to be striking at a given locality, 
but it generally makes its appearance soon if the beach is 
followed for any distance along the shore. Back of the town 
the great hooked spit at 170 feet on the south side of the 
Dawson road was found as described by Lawson. The most 
of the material for the spit appears to have been drawn from 
a hill of dritt wliich formed a salient point east of the road 
and above the town. At the top of the hill and just north of 
the road a lightly formed beach not mentioned by Lawson was 
found at about 210 feet. It takes the form of a gentle, boul- 
der strewn slope towards the south, and it iuis a low sea- 
elilf at its back. 
After crossing the first liill-top west of town on the Dawson 
road and descending the west side a large sandy beach ridge 
was crossed at 170 feet, the level of the hooked spit just noted. 
About five miles out faint sandy beaches were fouiid at 370 
and ,380 feet above the lake. A broad plain ;it 410 to 120 feet, 
eight miles out. may be related to a higher beach, but higlK-r 
ground was not seen in that vicinity. 
On a drive to the old Thunder Bay mine northeast of Port 
Arthur and up the north branch of Current river, several in- 
teresting evidences of submergence were observed. Starting 
northward from the post oltiee the road follows the tpri'ace of 
the Nipissing beach near its highest level to the outskirts of 
the town and then turns west through a cut in the old sea- 
cliff to the higher terrace. Less than a mile out a tine sandy 
beach running southwest is crossed b}^ the road at about 110 
feet above the lake. Clean-washed rounded gravel was found 
at 180 feet just south of tiie bridge over (^'urrent river. The 
gravel forms a plain and is part of an old delta, which is still 
more extensive on the north side of the river. Its surface 
slopes gradually towards the lake and is covered b}' a numer- 
ous series of low beach ridges of tine gravel and sand. The 
highest part cross<^d by the road is about 190 feet above the 
lake. About a mile northeast of the bridge an old lumber road 
turns off northward up the north branch of the river. This 
road crosses the outer edge of an old delta at about 210 feet.
