Isar Mountain is located right on the Canada/US border mostly south and just east of Cultus Lake.
To get there turn off Highway One and go south through Sardis and over the Vedder Bridge to Cultus Lake.
Then stay on the road that goes all the way back to the other end of the lake on the east side.
Next go left up a hill into Columbia Valley and follow it around where is looks like you have circled and heading back.
Watch for a Boy Scout Camp sign, and shortly after that a dirt road right off the paved road.
This is a old FSR road and is between privately owned property.
Go as far up the hill as you can depending what kind of vehicle you are driving and park because this is where you start hiking. There are a couple of barriers to go around blocking the road but keep going up this old FSR and it will climb up the side of Isar Mountain high above Columbia Valley. The map below shows a yellow road going to the yellow and red ribbon where the old road turns into a trail high up the mountain. Also at the end of the dotted red line it is mostly route finding because the trail get sketchy at best in most places getting to the Isar Mountain summit.
Deer on the road.
Morning mist coming off Chilliwack Lake and broken Robin egg on the road.
The old FSR with some Fungi and Shaggy Mane mushrooms.
Up on the trail and a view of the border cut line.
Some one had a camp hear before and left some pots and pans hanging in the tree.
He also had a shovel to help kill the camp fire when he was finished with it.
I took several GPS readings and pictures but only three were readable and I was not sure where they were taken but I think this one belongs at this place.
First look at Black Mountain in Washington State.
From the end of the trail I tried to continue to Isar's summit but instead came out in the logging cut block.
I did not realize at the time because the clouds were low and it was slightly raining that the cut block came right to the border.
At first I did not recognize anything that I was when the clouds finally dissipated.
Then I realized I was on the border at the edge of a logging cut block and had been looking south into the States.
I followed along the edge of the cut block heading to a high tree covered hill which I knew now was Isar's summit and then went into the trees. There were very old blazes on some of the trees and after taking a GPS reading I followed the blazes.
Then I was on the summit but the GPS readings showing in this picture are not high enough so I think I actually took this reading before I got there.
I tried to find some views from the summit and found only a couple of places to see views.
Then I went down the hill toward the border to look for some photo opportunities there and found a border marker monument. The border cutline could be clearly seen from it.
I remember taking a GPS reading there but the GPS was inaccurate and did not show exactly 49 degrees parallel and was slightly off.
Perhaps the previous picture of the GPS was done at the monument and not at the summit.
Still trying to get pictures I went west along the border cut line and finally got a view of the bump between Isar Mountain and Mount Amadis to the right and behind the bump.
Since I could not continue along the cut line because it turned into a rock buff and was to steep to go down and come up again I decided to head to the logging slash and get on the logging road and take some pictures from it.
Pictures from the logging road.
Unfortunately this road was not going where I hoped it would.
This Common Nighthawk was pretending to be hurt to lead me away from her nest.
Panorama showing the treed summit of Isar Mountain left where I came from and going right the high bump in between Isar and Amadis and behind right is Mount Amadis and the International Trail ends in the open area at it's top left corner.
On the right side of Mount Amadis is where I got to where trying to summit it from Liumchen Creek FSR and right is the western branch of Liumchen Creek Valley. Far in the back drop is Church Mountain, the Canada one and in front right is the border cut line.
Panoramas showing more of the logging roads and valley for better route finding next time.
On the border showing the cut line going up Liumchen Mountain to it's summit.
More panos and picture of the BC side of the border and view of some of Cultus Lake in the saddle.
Pictures showing close up of the border cut line and Church Mountain as a back drop behind the ridge in front.
Random pictures behind me looking into Washington State showing the bump of Canyon Ridge in the first few pictures left below and then showing Bald Mountain which is what I was looking at when I hiked up Liumchen Creek Valley but this time there is no snow on it.
Twin Sisters Mountain in the far distance which is west of Mount Baker in the US.
More pictures and panoramas of Canyon Ridge in the US.
Panorama of Canyon Ridge left and Bald Mountain right.
This is Church Mountain in Washington State, the US one.
Some random pictures and pano around where I am at.
Panorama showing left side is Church Mountain in BC and center left back is the border line going up Liumchen Mountain and right is some of Canyon Ridge.
Panorama showing left is this end of Canyon Ridge bump behind the tall dead tree and left and back left left with the pointed subpeak going way over to the right is Church Mountain in Washington State.
Now high enough to see above and beyond where I spent the night on the ridge of Chilliwack Lake and mountains that are in Canada toward the west except Middle Peak on left side of the right picture below which is in the US.
The low bump left of Bald Mountain is the very far end of Church Mountain Ridge and Bald Mountain is on the right edge of this pano below.
Good picture showing Church Mountain in Washington State, US.
The actual summit is the large block on the right side that was covered in clouds in the previous picyures and panos.
The picture on the right below is showing the western ridge bump of Church Mountain Ridge, US and then Mount Baker center and Bald Mountain front right.
I was walking back on the road and then left it to head toward the timber at the edge of the logging block.
Where I had come from.
A very smoggy picture toward the Strait Of Georgia in the very far distance. You had to be there to see it because this panorama did not do it justice.
Baker between the trees.
In the trees on the Canadian side of the border following some blazes again of a very faint trail.
Grassy meadow along the way going back.
On the hill where the pot, pans and fire pit are and where the trail going back ends.
Another view of Black Mountain in Washington State just down from the hill on the trail.
Another view of the US/ Canada Border Line. On the left is Washington State and right is British Columbia.
There is not much to this trail except I think you can get the closest pictures of Mount Baker from it than from any where else along the border in BC. It is also a great place to hike without bumping into any one since very few people hike this except maybe some people who live in Columbia Valley.
I think that the International Ridge Trail used to go through this way and perhaps farther into Washington State and got logged out since I seen old blazes and the remnants of an old trail.
Knowing this vehicles could be left at one end where the Internation Trail starts by the Cultus Lake trail head and others left in Columbia Valley and a hike can be done right through or from the Liumchen Creek FSR at the end of Vance Road trail head a vehicle could be left there and a loop can be hiked along the International Ridge Trail and then back on the series of old logging roads going down the Liumchen Creek Valley back to the vehicle or loop the opposite way.
See those trail reports of the International Ridge Trail and the one of Mount Amadis for more Details and directions.
