Alvin McDonald was not quite 18 when he started recording his cave explorations in a diary.

Click here to view the text of Alvin McDonald's diary, or click on the purple page descriptions to download a PDF of the pages associated with that month or topic. You can also look at individual pages by clicking on the page numbers to download a PDF of each handwritten page of his diary. Each page is a separate file (50-200 k). A good place to start is in January as earlier pages are mostly monetary accounts.

The months (in purple) contain all of the days listed to the side.

The pages are numbered consecutively as they are found in the diary; however Alvin skipped some numbers and duplicated others causing some confusion.

Natural Entrance of Wind Cave

Winds caused by changes in barometric pressure are what give Wind Cave its name. These winds have been measured at the cave's walk-in entrance at over 70 mph. The winds at the natural entrance of the cave attracted the attention of Native Americans and early settlers.
