Pasadena, California, has experienced snow a few times. In fact, Xavier Bias was out shopping at a Whole Foods in Pasadena when he saw a woman looking puzzled at the white stuff on the sidewalk. A native of the East Coast, he was more than happy to explain that snow falls at incredibly low elevations in Southern California. This snowfall, he said, was so low in elevation that it would fall near the foothills of the Sierra Nevada. In Pasadena, the rain and snowfall melted quickly and did not accumulate.

Last month, Pasadena was hit by an intense storm with hail and snow. Some residents mistakenly thought it was hail, but they were not deterred and stayed optimistic. When the hailstorm landed in Pasadena, it covered the streets, making them look like they’re in the Plains. However, the weather was still warm compared to other cities. The average rainfall and snowfall totals are higher than expected, and rain and snow are common.

In order to create a map of Pasadena, researchers analyzed two NASA satellite images of the city. The Landsat image was acquired on May 4, 2001, seven weeks before the summer solstice. Natural terrain shading is not prominent on the image because of the direction of view, and generally falls on the back side of a mountain range. To enhance the appearance of the city’s topography, the satellite image was processed to add topographic shading from an SRTM elevation model. A false sun illumination from the left enhances the appearance of the topography.

The area’s wells have long been contaminated with volatile organic compounds (VOCs) and perchlorate. However, this situation has changed. A treatment plant was built to remove these toxins and began operation in July 2011. Pasadena is also home to the Fuller Theological Seminary, the largest multidenominational seminary in the world. In 2018, the seminary announced plans to move its campus to Pomona by the summer of 2021. However, the campus will remain in Pasadena for now.
