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.read more

One of the first nice weekend days of the season, and the most humans visiting the mile that I personally have ever seen.read more

February 19, 2017 - [email protected]

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 land fallling into cove. Plenty of trash in cove, perhaps more than usual.read more

  • Tree falling further?
January 29, 2017 - [email protected]

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 seem to be any shortage of adult snails in the cove, by...read more

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.read more

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 I observed in a tide pool.read more
  • 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

Collected approx. 60lbs of litter, mostly plastics (see photo)Erosion of cliffs ongoing.read more

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 done a report when the slide actually started. Visit your miles regularly, people!)...read more
  • 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.

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 in the bluff resulting in tree fall and retreat in the bluff. Five people tidepooling. The two areas of concern...read more
  • 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

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 volume of human activity. Some of the 10 surfers were excited about the...read more
  • 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 - [email protected]
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 were at the tip of the furtherst north border of my mile. In addition to the...read more
  • 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.

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(crab) and kelp/algae in driftline. One dead unidentifiable bird. Sea lions trolling waters at mouth of cove. Moderate human impact...read more
  • 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.

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 on us. Only found 2 ochre sea stars (migrating to deeper waters in...read more
  • 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
  • 3 adult male Harlequins in breeding plumage, sunning on rock in 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!

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! Kelp/algae in driftline. Many hermit crabs without their shells...read more
  • 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...

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)-- walking, tidepooling, sitting or playing in sand. Two dogs.read more

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 into the mile. Rain water does not seem to bother sea anemones as several...read more

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. Observed Two Gumboot Chitons and many purple olive snails at a very low tide. Three to four dead crabs. Heavy human...read more

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 Cove tidepools. Heavy human impact (25)-20 exploring the tidepools, others sitting or playing in sand,4 dogs.read more
