Postcard from Mabel to Mrs. M. E. Wise, thanking her for her letter, sending her apologies that Mrs. Wise's father is unwell, and promising to explain why she will be unable to visit Boulder, Colorado until February. The front of the postcard features a photograph of two women standing on a large rock inside a dark cavern. Both women are wearing trousers and t-shirts, and the woman on the right has her hair pulled back into small draped turban. They are illuminated by a light from somewhere on the ground, which also reveals the large rock formations on the cave wall behind them. At their feet is a sign that reads, "Visit Cascade Caverns." The name of the cave, "Tobacco Room," is printed at the top of the postcard.
