SNOWFALL IN IOWA 1 849- 1868.
(By way of comparison.)
From the recorded observations of the celebrated Prof. T. S. Parvin, formerly of the State University of Iowa, now deceased, we have interesting data on the weather of Iowa. Previous to 1860 these observations were made at Muscatine and since that date at Iowa City. From Professor Parvin's recorded observations the following record of snowfall in eastern Iowa is taken:
| Snowfall | Snowfall | ||
|---|---|---|---|
| Year. | (in inches) | Year. | (in inches) |
| 1849------ | 9.41 | 1861 | 45.45------ |
| 1850------ | 7.90 | 1862 | 48.65------ |
| 1851------ | 18.00 | 1863 | 45.46------ |
| 1852------ | 50.10 | 1864 | 18.27------ |
| 1853------ | 16.30 | 1865 | 18.73------ |
| 1854------ | 12.50 | 1866 | 29.64------ |
| 1855------ | 46.10 | 1867 | 61.97------ |
| 1856------ | 54.40 | 1868 | 19.33------ |
| 1857------ | 35.10 | Mean | 33.23------ |
| 1858------ | 37.40 | Least | 7.90------ |
| 1850------ | 34.82 | Greatest | 61.97------ |
| 1860------ | 56.05 | ------ |
From this table it will be seen that the largest snowfall in eastern Iowa, according to these observations, was in 1867, with a total of 61.97 inches. The second largest snowfall was in 1860, with a total of 56.05 inches. The third largest snowfall, 54.04 inches, came in the celebrated winter of 1856, so often referred to by pioneers of Shelby.
