In January 2021, the Secretary of the Interior designated the Klagetoh Chapter House on the Navajo Nation in northeast Arizona a National Historic Landmark. Significant for its association with Navajo political leader and public health advocate Annie Dodge Wauneka, the chapter house was constructed in 1964 and employs native sandstone quarried near by. Wauneka gained election to the Navajo Tribal Council in 1951 and served in that body until 1979. In the 1950s, she led the Navajo effort to combat an epidemic of tuberculosis on the reservation and gained national attention and praise for her advocacy on public health matters. Wauneka was awarded the Presidential Medal of Freedom in December 1963. During the 2020 Covid pandemic, the chapter house served as a testing and supply distribution site. The project was undertaken by Front Range for the National Collaborative for Women's History Sites.

​Central/Keating Junior High School in Pueblo, Colorado, was listed in the National Register of Historic Places in December 2020. The school is significant in the area of Education, serving as Pueblo School District 20’s first and only junior high school from its initial construction in 1927 to 1954. The building continued as a junior high/middle school until its closure in 1982. The school reflects the district’s implementation of the 1910s and 1920s concept of educational reform through creation of the junior high school, an intermediate level facility between elementary and high schools that recognized the different social and educational needs of young teenagers. The school is also locally significant for its Architecture as a well-preserved example of the Classical Revival architectural style applied to educational buildings. It also is an illustration of a purpose-built 1920s junior high school building, including functional rooms reflecting then new teaching methods and curriculums. The school is further locally significant as a work of Pueblo architects William W. Stickney (1922 central part) and Walter F. DeMordaunt (1929 east and west wings). 

Maxwell Park School. The 1912 Maxwell Park School southwest of Buena Vista was listed in the National Register in December 2020. The one-room country school is significant for its architecture and for the role it played in educating the children of surrounding ranchers. The building displays ornamental concrete block construction.

Riedel/Circle S Ranch Bunkhouse. The 1930s Riedel/Circle S Ranch  bunkhouse west of Buena Vista was listed in the State Register in September. The bunkhouse is for its association with dude ranching from ca. early 1930s to the ca. early 1940s. The building represents the growing popularity of dude ranching in Colorado, as it was formed by joining two existing buildings together, a ranch hand bunkhouse and a log cabin to provide accommodations for ranch guests. Jack W. and Harriet R. Riedel purchased the existing ranch property in 1930 and began dude/guest ranch activities during the summers. The building is further significant as an example of a Rustic-style dude ranch guesthouse/bunkhouse. The Rustic style was often employed in mountain settings for lodges, vacation homes, and other resort facilities. This building’s Rustic architecture displays log walls; a gable roof; a full-width porch with log posts, bracing, and railing facing a scenic view; and multiple entrances on the front, some featuring ornamented Dutch wood doors

Irving Barn. The ca. 1886-88 Irving Barn south of Nathrop was listed in the State Register in September. The frame barn is significant in the area of Architecture as an example of an English frame barn in central Chaffee County, as reflected in its original rectangular shape, side-gable roof, board walls, upper story loft, and entrance on the wall of its long axis. James C. and Margaret S. Irving settled on the farm in 1886, and erected the barn. Mr. Irving became one of the most prosperous farmers in this section of Chaffee County, raising vegetables and livestock and adding more land to his holdings. The east addition illustrates the custom of adding onto an early barn to meet new needs. In this case the new space may have housed a vehicle, farm machinery, or storage space. 

On January 17th the Colorado Historic Preservation Review Board unanimously approved forwarding the National Register district nomination for the Coronado Lodge/Coronado Motel in Pueblo, Colorado. The 1940s motel is an excellent example of the Pueblo Revival style as applied to a roadside lodging facility. Four of the five principal buildings are constructed of locally produced adobe blocks. The property is also significant in the area of Ethnic Heritage/Black for its listing in the The Negro Travelers’ Green Book, a guidebook identifying facilities hospitable to black guests. The motel was listed in the Green Book from 1957 to 1967 and began welcoming African American guests in 1946.

This former White Spot restaurant in Denver's North Capitol Hill neighborhood was listed in the National Register on November 7th. The 1967 building was designed for the local coffee shop chain by Los Angeles architects Armet and Davis in the eye-catching Googie style . Front Range prepared the nomination in 2009, at which time the property was determined officially eligible. The owner objected to listing then, but has now consented. New photographs replicating the 2009 views were taken by Front Range. 

On February 4, 2019, History Colorado announced that the 2019 Governor's Award for Historic Preservation would be shared by Front Range Research Associates, the Park County Department of Heritage, Tourism and Community Development, Park County Historic Preservation Advisory Commission, Linda Balough (former director of DHTCD), Martorano Consutlants LLC, and Alpine Archaeological Consultants, Inc. for successful completion of a National Register nomination for the Tarryall Rural Historic District. The district includes 28,000 acres and twenty-five historic ranch headquarters along Park County Road 77. The district extends from south of Jefferson on US 285 to near Lake George on US 24. A video presented at the awards ceremony is posted on YouTube: www.youtube.com/watch?v=p6jDTWZQE54

Work on assessing the historical significance of the corridor began in 1995 with a survey by Alpine Archaeology. After becoming director of DHTCD, Linda Balough championed creation of a district to recognize the importance of this high altitude cattle and hay ranching area. Front Range was engaged to conduct historic resource surveys and prepare the National Register nomination. Marilyn Martorano assisted with vegetation analysis and archaeological resources. The National Park Service listed the district in the National Register in November 2017.

The National Park Service in Washington announced that the Gas Creek School has been listed November 26th in the National Register of Historic Places under the Rural School Buildings in Colorado Multiple Property Submission. The 1909 one-room country school, which served children of farm and ranch families of School District Number 20, is located near Nathrop in central Chaffee County, Colorado. Consolidation resulted in its closure in 1958. The project was undertaken for the Greater Arkansas Nature Association and the  Chaffee County Heritage Area Advisory Board under a State Historical Fund grant.
