Mount Lowell

Mount Lowell is a 3,150 metres (10,330 ft) mountain summit located in the Athabasca River valley of Jasper National Park, in the Canadian Rockies of Alberta, Canada. The name has not been officially adopted yet for this peak. It is situated at the head of Fryatt Creek Valley on the same high ridge as Mount Christie, Xerxes Peak, and Brussels Peak which is the nearest higher peak, 2.0 km (1.2 mi) to the north.[1] Mount Lowell can be seen from the Icefields Parkway.

History

The first ascent of the mountain was made in 1927 by Alfred Ostheimer with guides Hans Fuhrer and J. Weber.[2] Alfred Ostheimer named the peak after A. Lawrence Lowell who was a mountaineer and the president of Harvard University when Ostheimer climbed it.[2]

Geology

Mount Lowell is composed of sedimentary rock laid down from the Precambrian to Jurassic periods, then pushed east and over the top of younger rock during the Laramide orogeny.[3]

Climate

Based on the Köppen climate classification, Mount Lowell is located in a subarctic climate with long, cold, snowy winters, and short mild summers.[4] Temperatures can drop below -20°C with wind chill factors below -30°C. Precipitation runoff from Mount Lowell drains into Fryatt Creek and Lick Creek, both tributaries of the Athabasca River.

gollark: The stages of git clone are: Receive a "pack" file of all the objects in the repo database Create an index file for the received pack Check out the head revision (for a non-bare repo, obviously)"Resolving deltas" is the message shown for the second stage, indexing the pack file ("git index-pack").Pack files do not have the actual object IDs in them, only the object content. So to determine what the object IDs are, git has to do a decompress+SHA1 of each object in the pack to produce the object ID, which is then written into the index file.An object in a pack file may be stored as a delta i.e. a sequence of changes to make to some other object. In this case, git needs to retrieve the base object, apply the commands and SHA1 the result. The base object itself might have to be derived by applying a sequence of delta commands. (Even though in the case of a clone, the base object will have been encountered already, there is a limit to how many manufactured objects are cached in memory).In summary, the "resolving deltas" stage involves decompressing and checksumming the entire repo database, which not surprisingly takes quite a long time. Presumably decompressing and calculating SHA1s actually takes more time than applying the delta commands.In the case of a subsequent fetch, the received pack file may contain references (as delta object bases) to other objects that the receiving git is expected to already have. In this case, the receiving git actually rewrites the received pack file to include any such referenced objects, so that any stored pack file is self-sufficient. This might be where the message "resolving deltas" originated.
