At the age of 73 in 2013, Michel Molia – a retired dermatologist from Bayonne – started with his own quest for the bordermarkers of the Pyrenées including starting his own website.
And recently the Pyrénées Magazine published a nice article about him:

I met him several times with as a peak experience our trip to find the long lost intermediate bordermarkers bm408 III and IV. That they were found at last was only possible by his persistent search in the archives for a lost map.

I like him with his endurance, friendliness and wit. Now he has written his own bordermarker-guidebook and I was honored to receive a copy of his privately published book. It describes his trips, gives practical advice and is a pleasure to read. In a way, it is a printed version of the ‘guide’-part of his website. You might email him (michel.molia@free.fr) if you are interested in a copy.

He is not the first to make his own account of his bordermarker-quest. I have copies of privately published books by Jean Hirschinger/ Simone Hondelatte and Lucien Thomas. But Michel is the first to cover the entire esfr-border.
