No,

isn't it D.) Red River Valley

Red River Valley

To determine the key geographic feature explored by Thomas Nuttall's expedition, we can analyze the options presented. The Kiamichi and Poteau Rivers are already mentioned, so we need to determine the remaining feature. Let's go through the options:

A. Great Sand Dunes: While the Great Sand Dunes are a notable geographic feature in the United States, they are not mentioned in relation to Thomas Nuttall's expedition. Thus, we can eliminate this option.

B. Winding Stair Mountains: These mountains are a possibility, but we lack the necessary information to confirm if they were indeed explored by Nuttall's expedition. We should keep this option in consideration until we analyze the remaining options.

C. Wichita Mountains: This option does not match the blank space in the question, so we can eliminate it.

D. Red River Valley: The Red River Valley was not specifically mentioned in the question, so we need to assess if it could be a potential geographic feature explored by Nuttall's expedition. The Red River Valley is in close proximity to the Kiamichi and Poteau Rivers, making it a likely candidate.

Given the information, it is highly probable that the correct answer is D. Red River Valley. However, since the question does not provide definitive evidence, we cannot be certain about the answer.
