Talk:Heart Mountain (Wyoming)

Untitled

I wonder how long the landslide lasted. Was it a matter of days? Years? Eons? If anyone knows, this would make a good addition to the article.

Just added new info that was in today's news. Researchers estimate it lasted 30 minutes. howcheng {chat} 23:14, 19 May 2006 (UTC)

Largest slide?

From what I can see, the Storegga Slide is much larger, although it happened on the ocean floor. An area the size of Iceland ( 100,000 km² ) slid in three slides, which makes the total are roughly 75 times greater the the slide that created Heart Mountain. Any comment on this is apprciated.

I just went by what the source said. Perhaps we call it "the largest landslide on land ever discovered"? howcheng {chat} 15:44, 22 May 2006 (UTC)

Actually, going back to the source, I see that it does say "the biggest rockslide on land ever discovered." I'll add that to the article. howcheng {chat} 15:47, 22 May 2006 (UTC)

Correction to the name of the mountain

The original name of this mountain was Hart Mountain (as in hart, or deer). I was never clear if the mountain was named for such a animal, or after some person with the last name Hart. As late as the 1950's and 1960's locals were still correcting the spelling, but it seems that the incorrect spelling has won out. Because of the Relocation Center there was a train stop there, and the railroad sign for the stop read "Hart Mountain" The Bureau of Reclamation, however, named their irrigation project there, and its feeder canal, Heart Mountain. 24.117.239.18 07:23, 12 July 2007 (UTC)

That's pretty interesting, but we'd need some sort of cited source to back that one up. If you can find a book or an online source that has that information, you should put it in the article. howcheng {chat} 16:12, 12 July 2007 (UTC)

Out of curiosity, I checked Wyoming maps as far back as 1885 and 1883 and they all showed the "Heart" Spelling for "Heart Mountain". One 1881 map showed it as the "Heart Mountains". Interestingly, the first mention for the Heart Mountain Fault, in 1918, that I have so far found, called them the "Hart Mountain" and "Hart Mountain Overthrust". However, a 1905 geological map of the Bighorn Basin, which documented the anomalous stratigraphy used "Heart Mountain" in describing the confused stratigraphy he found. Paul H.

Requested Photo Tag

I just added the requested photo tag - I think we should get some pictures of the mountain from the ground. :) There is a not very goot shot of it from ground level in the relocation center article, but I'll bet there are probably some better ones in the public domain. If not, we'll try to track down some Wikipedian in the Bighorn Basin or Cody to swing by and get us a shot. Its a hard mountain to miss. - CosmicPenguin (Talk) 17:28, 12 July 2007 (UTC)

I found a bunch on Flickr and have contacted one photographer to see if she will be willing to give us a photo. howcheng {chat} 18:04, 12 July 2007 (UTC)

Wow - thats perfect. Thanks! - CosmicPenguin (Talk) 22:40, 12 July 2007 (UTC)

According to Holliday et al. (2023) and Mayback et al. (2022), which contain summaries of current literature, the Markagunt gavity slide covers an area of 8,000 km² (3,100 sq mi), while the Heart Mountain gravity slide covers an area of 3,400 km² (1,300 sq mi). Therefore, the Markagunt gavity slide is bigger than the Heart Mountain gravity slide and the 2010 papers, 1996 paper, and the Largest Landslides in the World are all out of date as far what is the largest known landslide.

The largest known submarine landslide is Baiyun–Liwan submarine slide in the South China Sea. It has a surface area of about 35,000 to 40,000 km² (14,000 to 15,000 sq mi) and slid for a distance of about 250 km (160 mi) according to Zhu et al. (2019).

Also, when talking a about such matters, I typically qualify them with the word "known" as there is the possibility that are larger ones that scientists do not know about.
