Many original notes below identified data errors in a NRIS database version of 2013. It is possible some have since been corrected in NRIS, as evidenced by spreadsheets on listings up to June 28, 2022 and on removed properties up to June 28, 2022 available for download (as of November 25, 2022) at "Data downloads" page: https://www.nps.gov/subjects/nationalregister/data-downloads.htm. I have downloaded copies of those. Henceforth call the listings one "Data-download-listings-2022-06-28". --Doncram (talk,contribs) 19:55, 25 November 2022 (UTC)[reply]
Boulder County Courthouse's Additional Documentation of 2018, with refnum=AD80000878, is included as 17 pages within main NRHP document in NPS's 187-page version,[1] but it is not included in NARA's version of NRHP nomination, a 166-page PDF, which includes 1978 text and photos but not 2018 AD. That will be fine, and even better, if the Additional Documentation gets posted by NARA, but it is not there now, when search on 80000878, AD80000878, other. --Doncram (talk) 20:29, 25 October 2022 (UTC)[reply]
The documentation for this was discussed at wt:NRHP, at Boulder_County_Courthouse item within this version of wt:NRHP. Editor 25or6to4 was the one who found the AD doc hidden within the NPS version. --Doncram (talk,contribs) 00:07, 27 November 2022 (UTC)[reply]
It is in 20220628 spreadsheet still as "Loveland State Amory", needs fix to Armory. NRHP registration document uses Loveland State Armory, so this appears to be a typo in NRIS entry. --Doncram (talk) 03:29, 23 September 2022 (UTC)[reply]
In Pueblo County, an NRIS name per NRHP infobox generator is "Indian Petroglyphs and Pictographs", but that doesn't seem like a very defining name, and National Register of Historic Places listings in Pueblo County, Colorado was set up to create article at Turkey Creek Canyon Rock Art District. History Colorado page title is "Indian Petroglyphs & Pictographs / Turkey Creek Canyon Rock Art District". How was this listed in NPS weekly announcement of listings? It was listed May 3, 1976, has 480 acres (190 ha) area, refnum = 76000566. What should name be, and should there be a name change? --Doncram (talk) 02:04, 25 October 2022 (UTC)[reply]
Weekly list PDFs at NPS go back only to 1988, but Federal Register this 1979 Federal Register PDF document list starting page 225 or so, states all listings previous to 1979. Under Colorado / Pueblo County, here is what is listed for it: "Penrose vicinity. INDIAN PETROGLYPHS AND PICTOGRAPHS, E of Penrose, (5-3-76)". For comparison other items are "Pueblo. BAXTER HOUSE, 325 W. 15th SL, (2-17-78)" and "Pueblo. PITKIN PLACE HISTORIC DISTRICT, S side of 300 block W. Pitkin PL, (1-31-78)". So it seems to be NRHP-listed as "Indian Petroglyphs and Pictographs". Further to me it seems that Turkey Creek Canyon Rock Art District (currently a redlink) is indeed the better article name, and that Indian Petroglyphs and Pictographs (currently a redlink) should redirect to that. The NRHP article should show "Indian Petroglyphs and Pictographs" in bold in the lede and that is what should appear in an NRHP infobox. --Doncram (talk) 02:25, 25 October 2022 (UTC)[reply]
Phillips Brothers Mill, which is located in Oak Run, California, in Shasta County, California, refnum 02001406, also has an NRHP listing given in Oak Run, Colorado, in Shasta County, Colorado, with listing status DR, refnum 02001255. This information seems to have been entirely wrong, and to have been corrected in the later California one's listing. Should the register entry be deleted? It's informative about what DR status can mean, i guess. --doncram (talk) 14:39, 28 March 2010 (UTC)[reply]
It shows only in Shasta County, Colorado, in 2022 NRHP spreadsheet. --Doncram (talk) 01:36, 26 October 2022 (UTC)[reply]
Francisco Plaza is misidentified as being in "Le Veta", when in fact it is located at 312 S. Main St. in La Veta, Colorado. It's to be La, not Le. Lamme Hospital, on the same street, is correctly identified as being in La Veta. doncram (talk) 07:38, 5 February 2009 (UTC)[reply]
Colorado has it at "Address: 2400 Curtis, Denver2400 Curtis, Denver" (cut&paste) ""Address: 2400 Curtis, Denver2400" is what i see which is a bit garbled. HC Temple Emanuel
Enterprise Hill Historic District in Denver is listed as being "Bounded by 21st and 22nd Aves., Tremont and Glenarm Pls". Neither Tremont nor Glenarm intersect either 21st or 22nd Aves., and NRIS-provided coords place this district between Tremont/Glenarm and 21st/22nd Sts., which are quite different from 21st/22nd Aves. Correct 21st and 22nd Aves. to 21st and 22nd Sts. Nyttend (talk) 14:30, 1 August 2009 (UTC)[reply]
The Motor Coach Division Building-Denver Tramway Company is listed at 3500 Gilpin Street, but this is a vacant lot. I took a picture of this building, and it is on the north side of 35th Avenue between Franklin and Gilpin streets. The picture is here. The address of the building is really on 35th Avenue, but none was visible on the structure. The grass in the photo is at what would be at 3500 Gilpin Street.
This is listed as ADDRESS RESTRICTED in 2022 NRHP spreadsheet, that should be changed. --Doncram (talk) 01:49, 26 October 2022 (UTC)[reply]
The address for the Manhattan Hotel in Salida, Chaffee County is listed as 225 F. Street, but the building there doesn't match the description. I think the building is really along the river at 228 N. F Street. Jeffrey Beall(talk) 23:36, 20 October 2011 (UTC)[reply]
The Methodist Episcopal Church is listed at 1414 Colorado Boulevard in Idaho Springs in Clear Creek County, but there isn't a building with that street number. There is a church at 1410 Colorado Boulevard, but it doesn't match the description found here. However, there is a church that does match the description at 1440 Colorado, Boulevard. See Google Maps. I think that is the church in question. Jeffrey Beall(talk) 21:17, 22 October 2011 (UTC)[reply]
Temple Emanuel (Pueblo, Colorado) is listed in NRIS2013a as being at 1425 N. Grand Ave. while in fact it is at 1325 N. Grand Ave. The NRHP document shows 1325. Google maps shows 1325. --Doncram (talk) 00:15, 6 June 2021 (UTC)[reply]
The Wheeler House, located at 1917 W. 32nd Avenue in Denver, has apparently been destroyed: this picture shows the site, which is obviously not occupied by the Late Victorian house from 1875 that is listed on the Register. Nyttend (talk) 01:00, 16 October 2009 (UTC)[reply]
The "New" Wolcott Bridge. According to one of the Colorado Historical Society's webpages (http://www.coloradohistory-oahp.org/programareas/register/1503/cty/ea.htm#wolcott but URL no longer works in 2022]), the Wolcott Bridge was replaced with a new one in 2005. I guess its removal hasn't made its way through the process yet. I went there to photograph it and learned later about its removal. Jeffrey Beall(talk) 13:03, 16 November 2011 (UTC)[reply]
This one is truly demolished, lots of reporting in its Wikipedia page.
NRIS shows "Black Squirrel Creek Bridge" still listed, in spreadsheet downloaded by me 2022-06-28. --Doncram (talk) 16:43, 25 October 2022 (UTC)[reply]
What evidence demolished? Note Addresses report below "St. Charles Bridge (Pueblo, Colorado) is listed as being on County Road 65, but I found the bridge to be on 27th Lane." Did i just look on wrong road? But how get 2006 year? --Doncram (talk) 22:57, 25 October 2022 (UTC)[reply]

I did try with NPS NRHP to get these coordinates updated, but i think got no reply, and on coordinates in general we chose to update on our own.
We now have improved coordinates for many (most?) Colorado NRHPs. Does Colorado SHPO have improved coordinates? --Doncram (talk) 16:50, 25 October 2022 (UTC)[reply]
The style of architecture for the Ogden Theatre in Denver is given as "Late 19th And 20th Century Revivals, Mediteranian Revival" — need to correct the spelling of "Mediterranean". Nyttend (talk) 13:04, 3 June 2009 (UTC)[reply]
Charles H. Stickney House, Pueblo, Colorado. Architect name correction to William Halsey Wood not Wm Halsey Ward is needed. Multiple other NRHP listings nationwide, of buildings of this era, list William Halsey Wood, so i believe this is just a typo here, to be corrected. --doncram (talk) 14:16, 23 June 2010 (UTC)[reply]
Union Pacific Railroad Julesburg Depot was built in 1930, was hit by a tornado in 1947, and was moved in 1974. All 3 should probably be identified as significant dates. Per an article generator derived from NRIS, though, 1947 shows up as the first date, and is suggested as the built date, while https://npgallery.nps.gov/NRHP/GetAsset/NRHP/04000019_text (the NRHP nomination) makes 1930 clear as the built date. --doncram 12:52, 16 May 2013 (UTC)[reply]
