TENTH REPORT. 
Algonquin and transition Beaches. 
In Saginaw as well as in Bay county we have apparently two old shore 
lines which represent halts and shore formations in the recession of this 
body of water. In the Bay county report this upper Algonquin beach 
has an elevation of from 610 — 623 feet A. T., bottom and top, while the 
lower built up beach ridge is from 593 — 610 feet A. T. The cut beach of the 
lower Algonquin in Bay county has an elevation of from 597 — 602, bottom 
and top. In Saginaw county this upper Algonquin beach, if such it proves 
to be, is more strongly and irregularly developed than in Bay county, while 
the lower beach is relatively undeveloped here in comparison with that shore 
line in Bay county. In the southern part of Bay county this lower Algon- 
quin beach is less strongly developed than in Bay City, and thence north 
from there. The following elevations are here given for what may repre- 
sent an Upper Algonquin beach in Saginaw county. 
In Brant, T. 10 N., R. 2 E., as follows: 
Section 23, north line, 616, top. 
“ 22, east “ , 616, “ 
“ 15, “ “ , 617, “ 
“ 28, “ “ , 617, “ 
“ 20, “ “ , 617, “ 
“ 23, “ “ , 620, “ 
The levels from Mr. Holmes give a much better differentiation for this 
township. 
Section 24, S. W. 621.3, top. 
« 24, S. E. U 622.9, “ 
“ 23, S. E. J, 614.9-622.3, bottom and top. 
Thence north into Fremont, Til N., R 2 E. there are the following ele- 
vations determined by Mr. Holmes. 
Section 34, east line, 624. A. T., top. 
“ 11, “ “ 625.3. 
“ 10, “ “ 626. 
“ 1, “ “ 628. 
Other determinations made with the wye level in this same township 
show beach formations at 611.3, 614.3, 6 i 7 . 3 , 617-619, A. T., at the top 
and it is quite probable that at least a portion are to be referred to a lower, 
more or less permanent elevation, of beach formation. 
In Richland, T 12 N., R 2 E. there is a beach having an elevation of 624 
feet A. T. at the top. 
Thence south and east into St. Charles, T 10 N., R 3 E. we get the upper 
Algonquin well defined from the lower beach at the following elevations: 
Section 19, S. W. 611.9-616.8, 620.3, bottom and top. 
“ 30, N. E. J, 617.8, top. 
“ 33, S. W. i, 618.3, “ 
Thence north again into Thomastown, T 12 N., R 3 E. we again get beach 
formations at irregular elevations. 
Section 33, east part, 606-614, bottom and top. 
“ 24, 617, top. 
“ 27 state road, 603.0-617.3, top. 
“ 4, east line, 620, top. 
“ 3, north “ 621, “
