Latest Notes

Note IDStart Time (US/Mountain)End Time (US/Mountain)EntrantNote
25055 27 Feb 2023 @ 1400 --- MAB little spouter near Africa from Sept 2021 still visible with gravel rim and tiny blips - may be more vigorous without Fireball flooding it
24503 28 Oct 2022 @ 1610 --- MAB and all day - Africa Area - small spouter from Sept 2021 near Africa seen blipping - with no waters flowing thru the area from Primrose Pinto & Fireball the rocks by Africa's vent are also visible
21209 06 May 2022 @ 0900 06 May 2022 @ 1300 MAB with Pinto active its hard to see the little spouter first spotted in Sept 2021 except for the gravel rim but as the day warmed up and when Pinto was low tiny blips were visible in the near-Africa spouter
21047 18 Apr 2022 @ 0945 --- MAB the rim of gravels surrounding the little spouter near Africa {first spotted in Sept 2021} was still visible - didn't see any blips with waters from Pinto flowing over that area - I left after Pinto was drained so don't know if it is still active when not drowned
18294 06 Jul 2021 @ 1215 --- MAB less water flowing thru the area now from around the berm & Pinto so Africa is now slightly visible w Colloidal blue water different from the surrounding water color
10719 04 Nov 2018 @ 0908 04 Nov 2018 @ 0957 MAB Visible blips and small burps from Africa - runoff from upstream still flows right over it so I thought that was something. In a blizzard. On the last day.
3305 14 Jul 2016 @ 1032 --- MAB Seen full today - with Pinto seen active today I wonder if when I saw it empty last Saturday that the stars (and geysers) had aligned and both Pinto and Fireball were done and not sending runoff downslope to its crater prior to my visit. Will investigate further!
3275 09 Jul 2016 @ 1850 --- MAB Drained. Water from uphill still empties into it, so I don't think it was from a change in flow uphill but I have never seen that empty! Will check Norris logs to see if they saw anything since I have been there.
1114 11 Jul 2014 @ 0000 11 Jul 2014 @ 2359 MAB I observed a vent at or near the Africa site on July 11, 2014.  This may not be new; runoff from above may have changed making it more noticeable.  Currently Pinto's milky blue water flows into it making it stand out.  Between Pinto eruptions you can see the crater, reddish edges, and sometimes slight convection.  I have sent photos from all angles to TSB and will get Rocco to look at it. For now, it's worth watching. If Africa did indeed clear out its vent, or if it is something new, either way it is intriguing. If it is a geyser, it may have more of a chance or at least be more interesting to observe if or when Pinto stops erupting and flooding the crater. 
Edited 8/18/2014: Photos sent to Scott earlier, and Rocco saw it today in person. Both concur this is very near, or the location of Africa.  
30033 19 Jun 1996 @ 1200 --- research-mab 6/19/1996 - no time noted - Little Africa (that developed last year) is getting much larger with the large rock in its center really moving with the water pressure.
30465 10 Sep 1992 @ 1200 --- research-mab 9/10/92 - no time noted - Africa Geyser’s vent is full of runoff water from up basin – it has formed a milky blue pool that fills the old vent. Blue is erupting dramatically today – could this be where the water has come from to fill Africa? All else seems “normal”
30733 07 Sep 1989 @ 1200 --- research-mab 9/7/1989 - no time noted - Africa – still quiet with multi-colored algae stained stalactites dripping in.
33433 06 Oct 1986 @ 1200 --- research-mab October 6, 1986 - no time noted - *The first algae bed along the boardwalk...runoff from Fireball and Africa… is completely mudded over with grey clay. There seem to be fresh holes (sputs) in the runoff.
7637 26 Jun 1986 @ 1800 --- research-mab 6-26-1986 Africa Geyser – Dormant, sinter formation around vent is heavily weathered. Water level in all 3 vents rises & falls in unison between 40-60cm below rim. Serves as drain for Pinto G., Lava Pool Complex,& features in part of the southeast portion of Porcelain Basin. Water in vents opalescent blue. T=125ºF
31161 29 Aug 1983 @ 1200 --- research-mab 8/29/1983 temperatures - no time noted - Africa Geyser – back vent has clear water cascading into vent, water level 6” down from surface 144º middle vent – water cascading in from back vent, a full “pool”, clear, 133º front vent- full “pool”, clear, 142º
31049 19 Feb 1983 @ 1200 --- research-mab 2/19/1983 - no time noted - Africa Geyser 122º slightly turbid & pulsating
31340 17 Jul 1982 @ 1200 --- research-mab Some Temps from Porcelain Basinland taken on July 17th - no time noted - Africa 140º light blue cloudy H20 that pulsated
31216 15 Jan 1982 @ 1200 --- research-mab January 15th, 1982 - no time noted -Africa Geyser old vent receiving runoff 140º new vent 128º
31589 11 Dec 1981 @ 1200 --- research-mab Dec 11 1981 - no time noted - Africa old vent 142º turbid gray H20. New vent 164º receiving runoff H20 from Porc Terraces.
31549 10 Sep 1981 @ 1200 --- research-mab 10 Sept 1981 - no time noted - Africa 166º water pouring in, vent empty top 8”
31520 14 Aug 1981 @ 1200 --- research-mab 14 Aug 1981 - no time noted - I saw no water in Africa geyser crater. {see Sunday Note}
4659 07 Aug 1981 @ 1800 --- research-mab 8/7/1981 Today I saw no water in Africa’s crater. If it is still filling in concert with Sunday’s majors it certainly isn’t visible from the boardwalk. GS
31462 02 Aug 1981 @ 1200 --- research-mab Sunday August 2 1981 - no time noted - Africa Geyser – continued filling up as Sunday Geyser went into period of low boiling. Water entering 118ºF, water in vent during fill up- 140ºF
31424 05 Jul 1981 @ 1200 --- research-mab Sunday July 5 1981 - general - See fill times in Sunday G eruptions - The beginning of Sunday’s majors are still synchronous with Africa’s fill. However, they last well after Africa’s drain. Africa’s fill is only sometimes high enough to be seen from the walk, but each time it tries {?}, it has been synchronous with Sunday’s major start.
33727 30 Jun 1981 @ 1200 --- research-mab 6-30-81 - no time - Norris Geyser Basin Measurements: Africa Geyser NE-SW 5.3m NW-SE (width) 6.6m Distance from Sunday G to old Africa vent 58m (New vent ruptured 1/81) to new Africa vent 55m
4629 19 Jun 1981 @ 1630 --- research-mab 6/19/1981 Grover S: Sunday’s majors are not coinciding as tightly with Africa’s fills. The majors start approx. when Africa’s level rises, but don’t end when Africa starts to ebb. They last well after the start of the drain in Africa. Eruptions are gaining power, reaching approx. 30 feet. Water from Sunday is milky. At 1623:15 Africa only filled enough to be barely visible from boardwalk. When Sunday’s major stops, the action now dwindles to a boil for several minutes. Then 3ft play starts which gets to 5-6 ft shortly before going into a major. Africa never did overflow the entire time I observed. Got to roughly 2 inches from top on all but the last at 1626:15
4623 03 Jun 1981 @ 1800 --- research-mab 6/3/1981 Africa – Dormant except for periodic heavy overflow
4606 02 Jun 1981 @ 1200 --- research-mab 6/2/1981: - no time noted - Africa Geyser was dormant all morning, except for periodic overflowing and minor splashing to two feet. It was active yesterday (6/1) with half minute periods of full eruption hitting 60 feet. In the late afternoon Africa reactivated with muddy eruptions to 60 feet coming about every half hour and lasting approximately 30 seconds.
33726 29 May 1981 @ 1200 --- research-mab 5-29-81 - no time - Africa vents surficially merged – top sinter sheet extensively shattered. Water very turbid & med gray-brn. [NOTE rupture occurred sometime in January no exact date known. Field date above - loose page not in bound field logs]
4614 22 Sep 1980 @ 1800 --- research-mab 9/22/1980 Africa Africa Geyser is having much shorter cycles and seems to be in the strong phase a greater percentage of time 179ºF
4603 14 Sep 1980 @ 0000 --- research-mab 9/14/1980 Africa – Heavy water phase eruptions seem to be getting stronger- water peak up to 80 feet. Intervals have increased to 40 minutes
31747 09 Sep 1980 @ 1200 --- research-mab Tuesday Sept 9 1980 - no time noted - Africa Geyser – 192° during weaker part of eruption
4969 14 Jul 1980 @ 1800 --- research-mab 07/14/1980 Constant was active again today, saw two 7 to 10 second eruptions. Set up a base line of 80 feet from Africa to measure maximum eruption height. For the first heavy period a burst hit 58 feet. During the second heavy period, two bursts reached 62 feet. Africa is going higher than we previously thought.
5082 22 Jun 1980 @ 1800 --- research-mab 06/22/1980 Africa was in a high H20 phase for 8 minutes, and then receded for 13 minutes until the next “high”occurred.
4973 18 Jun 1980 @ 1200 --- research-mab 06/18/1980 - no time noted - Africa erupting at a 30-35 minute interval with 5-7 min eruptions
4974 12 Jun 1980 @ 1230 --- research-mab 06/12/1980 Africa was in its high water phase when Bear Den erupted. Africa had a 10 minute interval between eruptions.
4977 08 Jun 1980 @ 1800 --- research-mab 06/08/1980 Africa Geyser – again cyclic this year, 170ºF during strong water phase
5076 01 Jun 1980 @ 1800 --- research-mab 06/01/1980 Africa appears cyclic again.
32021 05 Oct 1979 @ 1800 --- research-mab October 5 1979 - no time noted - The Whirligigs performing in dual, strong eruptions seems to be the present pattern. Africa was powerful while both were erupting, but diminished when Big Whirligig quit.
5072 04 Oct 1979 @ 1800 --- research-mab 10/04/1979 Africa & Fireball alternating nicely.
5074 27 Sep 1979 @ 1800 --- research-mab 09/27/1979 Africa – more periodic, but always has water spouting.
31998 27 Sep 1979 @ 1200 --- research-mab September 27 1979 - no time noted - Africa – more periodic, but always has water spouting.
4993 22 Sep 1979 @ 1800 --- research-mab 09/22/1979 Africa is slightly more cyclic, but is not quitting altogether as it did before the disturbance.
31975 21 Sep 1979 @ 1200 --- research-mab Friday September 21 1979 - no time noted - More end of summer changes! The out flow of dark, muddy water from Porcelain Basin has diminished from yesterday evening. Africa, Fireball, Arsenic and Geyser north of Constant all perpetual spouters.
4999 20 Sep 1979 @ 1800 --- research-mab 09/20/1979 Disturbance Africa Geyser – appears to have lost the cyclic behavior observed this summer erupting constantly 15 to 40 feet with moderate overflow.
5000 13 Sep 1979 @ 1200 --- research-mab SEPT 13 1979 - no times noted - Africa extremely cyclic today – steaming periods had no sprays of water
5057 10 Aug 1979 @ 0900 --- research-mab 08/10/1979 Africa was so loud this morning and with the basin full to the brim with fog, Helen and I thought Ledge had to be going. Quote Helen “Ledge started only a few minutes ago!” A mad dash through the thick white vapors left me sprayed by the water coming off of a noisy Africa. Ledge, as normal, was gently steaming.
31879 28 Jul 1979 @ 1200 --- research-mab July 28 1979 - no time noted - The crack below Africa’s run-off channel seems to be quieting down. The new geyser (or spouter) has decreased form 190º down to 180º. New Frying pan fumeroles are appearing next to the run-off channel of Africa.
5050 21 Jul 1979 @ 1800 --- research-mab 07/21/1979 The interval between major water phases of Africa was 34 minutes.
5036 19 Jul 1979 @ 1800 --- research-mab 07/19/1979 Africa was very cyclic today with powerful 40’ plus bursts soaking the entire vicinity followed by periods of steaming without water. Times between heavy surging were approximately 20 minutes.
31872 15 Jul 1979 @ 1200 --- research-mab July 15 1979 - no times noted - Africa is definitely becoming periodic again, about 20 min. between periods of heavy water.= {later note same day} - Africa – only steam
5034 14 Jul 1979 @ 1030 --- research-mab 07/14/1979 Africa sounds louder and is sending powerful bursts up to 35-40’.
5035 13 Jul 1979 @ 1800 --- research-mab 07/15/1979 Africa is definitely becoming periodic again, about 20 min. between periods of heavy water.
31869 11 Jul 1979 @ 1200 --- research-mab July 11 1979 - no time noted - In the runoff from Africa area, a couple of noisy frying pan spouters have come up, killing the surrounding algae
5008 25 May 1979 @ 1800 --- research-mab 05/25/1979 Africa Geyser – definitely cyclical, water phase very impressive much water up to 50’, steam phase still has some water although on occasion dies away to almost nothing 30-60 min per cycle
7659 24 Jan 1979 @ 1800 --- research-mab 1/24/1979 Africa’s ice formation 9’ high reaches with in 16’ of edge of Constant Geyser’s pool, overhanging middle fork of Tantalus Creek T=112F by 15½ ft from its base. 5 other ice cones present.
4953 13 Dec 1978 @ 1800 --- research-mab 12/13/1978 RICK H Africa – behaving as a true geyser with activity similar to Fred’s November 6th entry. Predominant source of water seemed to be major 3-5meter high eruptions out of Fireball Geyser. The ice formation near Africa is approx. 1.2 m tall; other ice, frost, snow & ghost tree displays in the basin are spectacular – especially by moonlight.
5099 06 Nov 1978 @ 1800 --- research-mab 11/06/1978 Biggest surprise was finding Sand Spring in eruption at 1616. Bursts of water were hitting 2 to 3 feet, considerable water was flowing into Pinwheel. Temp 195ºF Africa had long periods where the water was only be [sic] ejected 1 to 2 feet. Porcelain Basin was quiet when I arrived. Africa’s temp 166º ie
32207 14 Sep 1978 @ 1200 --- research-mab 09/14/1978 - no time noted - Africa has become milky brown

4962 22 Jun 1978 @ 1800 --- research-mab 06/22/1978 Africa seems to be having longer periods of quiet/erupting up to a foot or so for 5-10 seconds. Fireball seems to be decreasing in activity also.
4965 01 Apr 1978 @ 1200 --- research-mab 04/01/1978 Africa in a powerful water phase most of the morn.
4963 26 Mar 1978 @ 1800 --- research-mab 03/26/1978 Africa has been in a water phase these two days, sprays reaching heights of 10’15’
