Activity Comments:
I will note here that I actually started my observations at 12:39, but I finished up more about 2:00 p.m.

Stranded:
Fish & Invertebrates:
Driftline:
Kelp or Algae·Wood pieces·Ocean-based debris (from fishing boats, ship trash, etc.)
New Development:
Modifications:
Natural Changes:
Two seasonal waterfalls flowing briskly surely contributing to ongoing erosion.
Comments:

I sent an email to Jesse with a picture of what I think is the emerged nudibranch asking for a professional ID, but I haven't heard back yet.

Summary:

Fairly low tide during daylight hours on a dry day brought only a few visitors. Muddy trail access inspired creative entry points. Seasonal waterfalls flowing heavily. Observed a breeding pair of Harlequins out in the surf. I believe I saw an emerged nudibranch.

  • Low tide to compare to King Tide
    I can't resist posting a photo of the tidepools which were completely submerged during the King Tide which I last reported on.
    Taken from the access trail, looking toward the tidepools on the Northern margin of the South Cove.

  • worm trails on tide pool rocks
    The recent turbulent tides covered these tidepool rocks with enough sand for worms to inhabit

  • pale anemone
    I saw a couple green anemones which appeared very pale. I hope they are okay. I would expect this one to have closed up more as it is out of the water, but it was responsive to my touch.

2020

January 11, 2020 - alaingamerica
Though Cape Arago was receiving possibly record number of visitors, no one was trying to surf or otherwise visit South Cove. The tidepools were completely submerged, numerous driftwood were tossed by...
  • Submerged tidepools
  • Floating driftwood
  • Driftwood shifting in the surf
  • Most of access trail not impacted
  • Heavy visitation creates traffic

2019

December 25, 2019 - alaingamerica
I have always been curious what is happening at my mile during high tide. I generally go at low tide to access the most sand and tide pools I can.  Since Christmas day had a king tide, I did a brief...
  • King tide st South Cove
November 1, 2019 - alaingamerica
Nice day at the beach. Not many vistors despite the fair weather. Saw lots of crab shells in the wrack line. Not sure if it's a molt. See pix. Tide higher than when I normally visit.

February 17, 2019 - alaingamerica
A very nice day. Went to try and get better photos of the Harlequin group I saw last time, but if they were there, they were out of range for photos. My battery ran dead fairly soon anyway. I...

  • South Cove
January 26, 2019 - alaingamerica

2018

May 19, 2018 - JamieF
A beautiful day out, great low tide. People were respectful of the intertidal habitat. Having the watchful eyes of several OIMB graduate students on hand was no doubt a helpful factor.

2017

April 2, 2017 - alaingamerica
One of the first nice weekend days of the season, and the most humans visiting the mile that I personally have ever seen.
February 19, 2017 - alaingamerica
Just a cursuray visit. Saw four people and 1 dog in total. 3 vehicles in car park. Noticed lots of small plastic fragments in wrack line. Found a boat bumper (?) from Cape Sebastian. Wonder if more...
  • Tree falling further?
January 29, 2017 - alaingamerica
Not much evidence of the recent high tides. Found unusual to me things in the low drift line. An abundance of small snails on rocks. I myself murdered quite a few by walking out on the rocks. Doesn't...
  • red sea anemone

2016

January 1, 2016 - JamieF
Walked on beach southward along boulder field to furthest extent practical and returned. Mostly found refuse and very little/no marine bird or mammal remains.

2015

May 9, 2015 - alaingamerica
A high number of people for this mile, enjoying the low tide. Will be returning with a mission to track the number of sea stars and sea urchins. Will edit report once I identify the unusual creature...
  • This creature is roughly adult hand sized, rounded and firm to the touch. You can see the  hermit crabs that were dancing around on it's surface.
  • New trees down in slide" "Directly south of beach access trail
January 1, 2015 - JamieF
Collected approx. 60lbs of litter, mostly plastics (see photo)Erosion of cliffs ongoing.

2014

December 13, 2014 - alaingamerica
The big news is the landslide, which threatens the access trail to the south cove. The slide began last winter and continues to move. (I have been remiss in visiting my mile and wish I would have...
  • Was modified last spring after initial slide. Narrow, muddy, slick, unstable looking
  • There was ground water flowing on either side of the landmass.
  • Exposed tree roots. Wouldn't be surprised if it dropped before the winter is over
  • Probably exposed during initial slide.
  • Obvious slump of land detaching from main part of cliff
  • Beach access formerly went through this area, just uphill from here, the State put in railroad tie steps and switched the trail back
  • A memorial bench used to rest on this concrete pad. The State removed it before it could fall into the chasm. The trail is being undercut at the far edge of the concrete pad
  • a view across the chasm made by the landslide.
  • A small trail used to skirt the edge up top. No more.

2012

February 23, 2012 - junebugrudd
Everything was quiet and reasonably undisturbed. Kelp, shells, rocks, wood and land- and ocean-based debris in the driftline. Common Loons and dabbling ducks in the bay. Major cracks and landslides...
  • Major erosion of walkway down to the beach
  • Trees falling, more erosion
  • Tide pools alive!
  • Example of litter at this site
  • Healthy bunch of beach wrack

2009

December 23, 2009 - alaingamerica
Due to the tide height, this was not an ideal day for a CoastWatch of mile 116. Anything that might wash up was certainly submerged or floating in the cove. However, I was very surprised at the...
  • Note call numbers on plane. It was heard that this plane was associated with the group of 10 surfers visiting mile 116 on this day.
  • Majority of party of 10 surfers visiting mile 116. (and me in the blue coat)
  • I've learned that South Cove is in the very Northern part of their range, but it is unusual to see them at the beach!
October 3, 2009 - alaingamerica
The South Cove appears much as it always does, beautiful and serene. Only myself, my partner and two other visitors during my visit. I have never noticed Black Oystercatchers in the cove before. They...
  • top view of octopus remains found on beach this trip.
  • bottom view of octopus remains.
  • I think this guy lives in this area. I have a photo of another Heron from a previous visit. Maybe it's the same one?
  • I'd never noticed this snail before, so I'm posting it here.
May 25, 2009 - alaingamerica
Extremely low tide offered opportunity to look at rarely exposed areas. Found a vivid royal purple sea star. Overheard one tidepooler telling another she saw two dead sunfish. Many animal casings(...
  • A shot of south cove at a -2.4 tide.
  • Another shot, the north side of south cove. The most exposed rock I've ever seen there.
  • I was impressed with the coloration of this ochre sea star. I've never seen such a vivid purple. Hopefully it shows on the picture.

2008

December 5, 2008 - alaingamerica
Was able to positively identify ducks I saw last time as wintering Harlequins. Great Blue Heron was confident we would not be charging out over the rocks to harm it, though it did keep a watchful eye...
  • Great Blue Heron at South Cove, Cape Aragon, December 2008
  • GBH flies out to sea from South Cove, Cape Arago
  • Wintering Harlequin adult male in breeding plumage, swimming in the waters of South Cove, Cape Arago

  • Need help identifying this.  Was found in South Cove, Cape Arago. Is about the size of two digits of an index finger. Thank you!
September 21, 2008 - alaingamerica
This visit was a few months from my last visit. I found this quite helpful in observing how the piles of kelp I saw last visit are being broken down. My goal is to get to my mile much more frequently...
  • Pretty day, eh?
  • Another reference point. Pic looks like could have been taken at Leslie Gulch.
  • Such a nice day at the beach!
  • Sorry for poor quality. I needs me a telephoto and an idenfication guide...
June 22, 2008 - alaingamerica
Heavy thick mats of kelp and seaweed in driftline. State Parks ranger, who was guiding a tidepool walk, assured me large kelp piles were normal. Two dead purple shore crabs. Heavy human impact (42...
February 2, 2008 - alaingamerica
The mile looks much the same as last visit. It seems like a new tree has slid down the bluff. Erosion is continuing at northern border of mile 116. Five rain-fed waterfalls flowing at full force...

2007

June 16, 2007 - alaingamerica
Many people taking advantage of the very low tide. Oregon State Parks had a ranger guide people through the tidepools. I observed enthusiastic, but respectful exploring. Very light wrackline....
March 11, 2007 - alaingamerica
Was the first warm, sunnyish weekend day. Lots of people in love with the tidepools. Kelp/algae and land-based debris in driftline. Sunstars, urchins, chitons, pink anemone and seaweeds in South...
