One of them did acrobatic tricks and jumps, apparantly "for that one picture". Fairly dangerous terrain, especially considering that the mound still has an active vent, even if barely steaming on cold days, on top of it as seen from satellite imagery
16445 19 Oct 2020 @ 1501 --- JSJ Shock waves from a 7.5 magnitude earthquake arrived at Yellowstone's seismic network. The quake hit offshore from the Alaska Peninsula ~6.5 minutes earlier. See attachment.

14190 15 May 2020 @ 1601 --- JarnoO (wc) Something black ran from behind the trees behind Arrowhead on top of Little Cub and then (presumably, cam panned away too quickly) into the woods. Height of this animal didn't appear to be much taller than Little Cub's "cone on top of the cone". Also didn't appear to have a bison shape. Bear? EDIT: appears to have been a wolf per comments and chat page.
14189 15 May 2020 @ 1540 15 May 2020 @ 1554 JarnoO (wc) Herd of ≥25 bison on the meadow from Pump to behind Giantess. Part crossed the boardwalk toward Lion & Arrowhead Spring.

14171 12 Apr 2020 @ 0329 12 Apr 2020 @ 0348 Betty A huge steamcloud became visible above the treeline a bit to the left of the Lion Group. I have no idea about the source, but maybe something in Midway Geyser basin or Fountain Area erupting. I´ve never seen anything that huge from that area before. Addition: After watching the overnight capture it seemed to be the usual steam from Midway Geyser Basin in a cold night. Just the wind direction and moonlight made it appear that big.
14157 24 Mar 2020 @ 0655 24 Mar 2020 @ 0741 Kat Noted canid at 0655 enter meadow in front of OF Inn - came from Hams store area. Moving slowly looking back a number of times. Initially with darkness just lifting appeared to be coyote. It wandered around meadow slowly and then bedded. When animal began to move again it was clear that this was larger than a coyote and black. Lone black wolf then moved to old bison carcass area and bedded gnawing on old remains. Still in view at 0729. Began moving down basin at 0736 toward row of conifers in front of Castle. Moved behind trees and crossed Castle path and into the woods at 0741. This exit and path is exactly what we have observed with the Wapitis.

14112 03 Feb 2020 @ 1448 03 Feb 2020 @ 1530 JarnoO (wc) Two ravens eating from earlier-mentioned bison carcass. Coyote (probably the same of the 1432-1439 note) came back into frame @ 1500 and scared off the ravens. Coyote ran away @ 1515. One raven returned @ 1517, with the other one a minute or one-two later. Another two joined @ 1523. Ravens flew away @ 1530.
14111 03 Feb 2020 @ 1432 03 Feb 2020 @ 1439 JarnoO (wc) Coyote eating off a dead bison in the meadow front-left-ish of the Inn. After 1433 it moved across the Firehole and to the Lion Group. Thereafter it looked like it moved into the woods.
