Nordenskiold, a member of the Swedish nobility, had read of the Mesa Verde ruins and had decided to excavate some of them. In July 1891, he arrived at the Wetherill ranch and hired John Wetherill as his guide and foreman. Three more men were hired as laborers and for four months the group excavated in the cliff dwellings. Spruce Tree House bears Nordenskiold’s inscription, “Number 1 House.” Cliff Palace bears the inscription, “No. 2,” and in all, twenty-two ruins bear numbers left by Nordenskiold. The archeological specimens recovered by Nordenskiold were taken to Sweden but at the present time are in the National Museum, in Helsinki, Finland. In the collection, as cataloged today, are about 600 specimens. While it is a good collection it does not deserve the fabulous reputation it has acquired. Although Nordenskiold reached the Mesa Verde in 1891, the finest things had already been taken out by the cowboys. His collection contained a number of outstanding specimens but in its entirety did not compare with the collections taken out by the cowboys themselves. [Illustration: Spruce Tree House Spruce Tree House was the second large cliff dwelling discovered by the cowboys. Richard Wetherill saw it from the canyon rim on the same day that he and Charles Mason found Cliff Palace. His view on that wintry day of December 18, 1888, probably was much like this.] THE DISCOVERY OF SQUARE TOWER HOUSE After discovering Cliff Palace and Spruce Tree House, Richard Wetherill and Charles Mason returned to their camp. The next morning they started off to visit Spruce Tree House, which only Richard had seen the day before. As they rode across the snow covered mesa they misjudged their direction and bore too far to the south. Coming to the rim of a deep canyon they found, not Spruce Tree House, but another large cliff dwelling. Although not as large as the two they had found the day before it was still much larger than any they had seen previously. The outstanding feature of the ruin was a tall square tower, a four-story structure that rose against the cliff. Because of it they later named the ruin Square Tower House. The two men now began to realize the importance of their discoveries. During the past few years they had seen many small ruins along the Mancos Canyon to the south. Now they had pushed up the canyons to the north and in the space of two days had found not only the ruin Acowitz had called the “greatest cliff dwelling,” but two more large ruins. As they sat on their horses above Square Tower House they could see that off to the north and west were many more canyons. Surely more of the mysterious structures awaited discovery.
